Struct PathBuf

pub struct PathBuf(/* private fields */);

An owned, mutable UTF-8 path (akin to String).

This type provides methods like push and set_extension that mutate the path in place. It also implements Deref to Utf8Path, meaning that all methods on Utf8Path slices are available on Utf8PathBuf values as well.

Examples

You can use push to build up a Utf8PathBuf from components:

use camino::Utf8PathBuf;

let mut path = Utf8PathBuf::new();

path.push(r"C:\");
path.push("windows");
path.push("system32");

path.set_extension("dll");

However, push is best used for dynamic situations. This is a better way to do this when you know all of the components ahead of time:

use camino::Utf8PathBuf;

let path: Utf8PathBuf = [r"C:\", "windows", "system32.dll"].iter().collect();

We can still do better than this! Since these are all strings, we can use From::from:

use camino::Utf8PathBuf;

let path = Utf8PathBuf::from(r"C:\windows\system32.dll");

Which method works best depends on what kind of situation you’re in.

Implementations

impl Utf8PathBuf

pub fn new() -> Utf8PathBuf

Allocates an empty Utf8PathBuf.

Examples

use camino::Utf8PathBuf;

let path = Utf8PathBuf::new();

pub fn from_path_buf(path: PathBuf) -> Result<Utf8PathBuf, PathBuf>

Creates a new Utf8PathBuf from a PathBuf containing valid UTF-8 characters.

Errors with the original PathBuf if it is not valid UTF-8.

For a version that returns a type that implements std::error::Error, use the TryFrom<PathBuf> impl.

Examples

use camino::Utf8PathBuf;
use std::ffi::OsStr;
use std::os::unix::ffi::OsStrExt;
use std::path::PathBuf;

let unicode_path = PathBuf::from("/valid/unicode");
Utf8PathBuf::from_path_buf(unicode_path).expect("valid Unicode path succeeded");

// Paths on Unix can be non-UTF-8.
let non_unicode_str = OsStr::from_bytes(b"\xFF\xFF\xFF");
let non_unicode_path = PathBuf::from(non_unicode_str);
Utf8PathBuf::from_path_buf(non_unicode_path).expect_err("non-Unicode path failed");

pub fn into_std_path_buf(self) -> PathBuf

Converts a Utf8PathBuf to a PathBuf.

This is equivalent to the From<Utf8PathBuf> for PathBuf impl, but may aid in type inference.

Examples

use camino::Utf8PathBuf;
use std::path::PathBuf;

let utf8_path_buf = Utf8PathBuf::from("foo.txt");
let std_path_buf = utf8_path_buf.into_std_path_buf();
assert_eq!(std_path_buf.to_str(), Some("foo.txt"));

// Convert back to a Utf8PathBuf.
let new_utf8_path_buf = Utf8PathBuf::from_path_buf(std_path_buf).unwrap();
assert_eq!(new_utf8_path_buf, "foo.txt");

pub fn with_capacity(capacity: usize) -> Utf8PathBuf

Available on path_buf_capacity only.

Creates a new Utf8PathBuf with a given capacity used to create the internal PathBuf. See with_capacity defined on PathBuf.

Requires Rust 1.44 or newer.

Examples

use camino::Utf8PathBuf;

let mut path = Utf8PathBuf::with_capacity(10);
let capacity = path.capacity();

// This push is done without reallocating
path.push(r"C:\");

assert_eq!(capacity, path.capacity());

pub fn as_path(&self) -> &Utf8Path

Coerces to a Utf8Path slice.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let p = Utf8PathBuf::from("/test");
assert_eq!(Utf8Path::new("/test"), p.as_path());

pub fn push(&mut self, path: impl AsRef<Utf8Path>)

Extends self with path.

If path is absolute, it replaces the current path.

On Windows:

• if path has a root but no prefix (e.g., \windows), it replaces everything except for the prefix (if any) of self.
• if path has a prefix but no root, it replaces self.

Examples

Pushing a relative path extends the existing path:

use camino::Utf8PathBuf;

let mut path = Utf8PathBuf::from("/tmp");
path.push("file.bk");
assert_eq!(path, Utf8PathBuf::from("/tmp/file.bk"));

Pushing an absolute path replaces the existing path:

use camino::Utf8PathBuf;

let mut path = Utf8PathBuf::from("/tmp");
path.push("/etc");
assert_eq!(path, Utf8PathBuf::from("/etc"));

pub fn pop(&mut self) -> bool

Truncates self to self.parent.

Returns false and does nothing if self.parent is None. Otherwise, returns true.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let mut p = Utf8PathBuf::from("/spirited/away.rs");

p.pop();
assert_eq!(Utf8Path::new("/spirited"), p);
p.pop();
assert_eq!(Utf8Path::new("/"), p);

pub fn set_file_name(&mut self, file_name: impl AsRef<str>)

Updates self.file_name to file_name.

If self.file_name was None, this is equivalent to pushing file_name.

Otherwise it is equivalent to calling pop and then pushing file_name. The new path will be a sibling of the original path. (That is, it will have the same parent.)

Examples

use camino::Utf8PathBuf;

let mut buf = Utf8PathBuf::from("/");
assert_eq!(buf.file_name(), None);
buf.set_file_name("bar");
assert_eq!(buf, Utf8PathBuf::from("/bar"));
assert!(buf.file_name().is_some());
buf.set_file_name("baz.txt");
assert_eq!(buf, Utf8PathBuf::from("/baz.txt"));

pub fn set_extension(&mut self, extension: impl AsRef<str>) -> bool

Updates self.extension to extension.

Returns false and does nothing if self.file_name is None, returns true and updates the extension otherwise.

If self.extension is None, the extension is added; otherwise it is replaced.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let mut p = Utf8PathBuf::from("/feel/the");

p.set_extension("force");
assert_eq!(Utf8Path::new("/feel/the.force"), p.as_path());

p.set_extension("dark_side");
assert_eq!(Utf8Path::new("/feel/the.dark_side"), p.as_path());

pub fn into_string(self) -> String

Consumes the Utf8PathBuf, yielding its internal String storage.

Examples

use camino::Utf8PathBuf;

let p = Utf8PathBuf::from("/the/head");
let s = p.into_string();
assert_eq!(s, "/the/head");

pub fn into_os_string(self) -> OsString

Consumes the Utf8PathBuf, yielding its internal OsString storage.

Examples

use camino::Utf8PathBuf;
use std::ffi::OsStr;

let p = Utf8PathBuf::from("/the/head");
let s = p.into_os_string();
assert_eq!(s, OsStr::new("/the/head"));

pub fn into_boxed_path(self) -> Box<Utf8Path>

Converts this Utf8PathBuf into a boxed Utf8Path.

pub fn capacity(&self) -> usize

Invokes capacity on the underlying instance of PathBuf.

Requires Rust 1.44 or newer.

pub fn clear(&mut self)

Available on path_buf_capacity only.

Invokes clear on the underlying instance of PathBuf.

Requires Rust 1.44 or newer.

Available on try_reserve_2 only.

Invokes try_reserve_exact on the underlying instance of PathBuf.

Requires Rust 1.63 or newer.

pub fn shrink_to_fit(&mut self)

Invokes shrink_to_fit on the underlying instance of PathBuf.

Requires Rust 1.44 or newer.

pub fn shrink_to(&mut self, min_capacity: usize)

Available on shrink_to only.

Invokes shrink_to on the underlying instance of PathBuf.

Requires Rust 1.56 or newer.

Methods from Deref<Target = Utf8Path>

pub fn as_std_path(&self) -> &Path

Converts a Utf8Path to a Path.

This is equivalent to the AsRef<&Path> for &Utf8Path impl, but may aid in type inference.

Examples

use camino::Utf8Path;
use std::path::Path;

let utf8_path = Utf8Path::new("foo.txt");
let std_path: &Path = utf8_path.as_std_path();
assert_eq!(std_path.to_str(), Some("foo.txt"));

// Convert back to a Utf8Path.
let new_utf8_path = Utf8Path::from_path(std_path).unwrap();
assert_eq!(new_utf8_path, "foo.txt");

pub fn as_str(&self) -> &str

Yields the underlying str slice.

Unlike Path::to_str, this always returns a slice because the contents of a Utf8Path are guaranteed to be valid UTF-8.

Examples

use camino::Utf8Path;

let s = Utf8Path::new("foo.txt").as_str();
assert_eq!(s, "foo.txt");

pub fn as_os_str(&self) -> &OsStr

Yields the underlying OsStr slice.

Examples

use camino::Utf8Path;

let os_str = Utf8Path::new("foo.txt").as_os_str();
assert_eq!(os_str, std::ffi::OsStr::new("foo.txt"));

pub fn to_path_buf(&self) -> Utf8PathBuf

Converts a Utf8Path to an owned Utf8PathBuf.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let path_buf = Utf8Path::new("foo.txt").to_path_buf();
assert_eq!(path_buf, Utf8PathBuf::from("foo.txt"));

pub fn is_absolute(&self) -> bool

Returns true if the Utf8Path is absolute, i.e., if it is independent of the current directory.

• On Unix, a path is absolute if it starts with the root, so is_absolute and has_root are equivalent.

• On Windows, a path is absolute if it has a prefix and starts with the root: c:\windows is absolute, while c:temp and \temp are not.

Examples

use camino::Utf8Path;

assert!(!Utf8Path::new("foo.txt").is_absolute());

pub fn is_relative(&self) -> bool

Returns true if the Utf8Path is relative, i.e., not absolute.

See is_absolute’s documentation for more details.

Examples

use camino::Utf8Path;

assert!(Utf8Path::new("foo.txt").is_relative());

pub fn has_root(&self) -> bool

Returns true if the Utf8Path has a root.

• On Unix, a path has a root if it begins with /.

• On Windows, a path has a root if it:

  • has no prefix and begins with a separator, e.g., \windows
  • has a prefix followed by a separator, e.g., c:\windows but not c:windows
  • has any non-disk prefix, e.g., \\server\share

Examples

use camino::Utf8Path;

assert!(Utf8Path::new("/etc/passwd").has_root());

pub fn parent(&self) -> Option<&Utf8Path>

Returns the Path without its final component, if there is one.

Returns None if the path terminates in a root or prefix.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/foo/bar");
let parent = path.parent().unwrap();
assert_eq!(parent, Utf8Path::new("/foo"));

let grand_parent = parent.parent().unwrap();
assert_eq!(grand_parent, Utf8Path::new("/"));
assert_eq!(grand_parent.parent(), None);

pub fn ancestors(&self) -> Utf8Ancestors<'_>

Produces an iterator over Utf8Path and its ancestors.

The iterator will yield the Utf8Path that is returned if the parent method is used zero or more times. That means, the iterator will yield &self, &self.parent().unwrap(), &self.parent().unwrap().parent().unwrap() and so on. If the parent method returns None, the iterator will do likewise. The iterator will always yield at least one value, namely &self.

Examples

use camino::Utf8Path;

let mut ancestors = Utf8Path::new("/foo/bar").ancestors();
assert_eq!(ancestors.next(), Some(Utf8Path::new("/foo/bar")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("/foo")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("/")));
assert_eq!(ancestors.next(), None);

let mut ancestors = Utf8Path::new("../foo/bar").ancestors();
assert_eq!(ancestors.next(), Some(Utf8Path::new("../foo/bar")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("../foo")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("..")));
assert_eq!(ancestors.next(), Some(Utf8Path::new("")));
assert_eq!(ancestors.next(), None);

pub fn file_name(&self) -> Option<&str>

Returns the final component of the Utf8Path, if there is one.

If the path is a normal file, this is the file name. If it’s the path of a directory, this is the directory name.

Returns None if the path terminates in ...

Examples

use camino::Utf8Path;

assert_eq!(Some("bin"), Utf8Path::new("/usr/bin/").file_name());
assert_eq!(Some("foo.txt"), Utf8Path::new("tmp/foo.txt").file_name());
assert_eq!(Some("foo.txt"), Utf8Path::new("foo.txt/.").file_name());
assert_eq!(Some("foo.txt"), Utf8Path::new("foo.txt/.//").file_name());
assert_eq!(None, Utf8Path::new("foo.txt/..").file_name());
assert_eq!(None, Utf8Path::new("/").file_name());

pub fn strip_prefix( &self, base: impl AsRef<Path>, ) -> Result<&Utf8Path, StripPrefixError>

Returns a path that, when joined onto base, yields self.

Errors

If base is not a prefix of self (i.e., starts_with returns false), returns Err.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let path = Utf8Path::new("/test/haha/foo.txt");

assert_eq!(path.strip_prefix("/"), Ok(Utf8Path::new("test/haha/foo.txt")));
assert_eq!(path.strip_prefix("/test"), Ok(Utf8Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/"), Ok(Utf8Path::new("haha/foo.txt")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt"), Ok(Utf8Path::new("")));
assert_eq!(path.strip_prefix("/test/haha/foo.txt/"), Ok(Utf8Path::new("")));

assert!(path.strip_prefix("test").is_err());
assert!(path.strip_prefix("/haha").is_err());

let prefix = Utf8PathBuf::from("/test/");
assert_eq!(path.strip_prefix(prefix), Ok(Utf8Path::new("haha/foo.txt")));

pub fn starts_with(&self, base: impl AsRef<Path>) -> bool

Determines whether base is a prefix of self.

Only considers whole path components to match.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/etc/passwd");

assert!(path.starts_with("/etc"));
assert!(path.starts_with("/etc/"));
assert!(path.starts_with("/etc/passwd"));
assert!(path.starts_with("/etc/passwd/")); // extra slash is okay
assert!(path.starts_with("/etc/passwd///")); // multiple extra slashes are okay

assert!(!path.starts_with("/e"));
assert!(!path.starts_with("/etc/passwd.txt"));

assert!(!Utf8Path::new("/etc/foo.rs").starts_with("/etc/foo"));

pub fn ends_with(&self, base: impl AsRef<Path>) -> bool

Determines whether child is a suffix of self.

Only considers whole path components to match.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/etc/resolv.conf");

assert!(path.ends_with("resolv.conf"));
assert!(path.ends_with("etc/resolv.conf"));
assert!(path.ends_with("/etc/resolv.conf"));

assert!(!path.ends_with("/resolv.conf"));
assert!(!path.ends_with("conf")); // use .extension() instead

pub fn file_stem(&self) -> Option<&str>

Extracts the stem (non-extension) portion of self.file_name.

The stem is:

• None, if there is no file name;
• The entire file name if there is no embedded .;
• The entire file name if the file name begins with . and has no other .s within;
• Otherwise, the portion of the file name before the final .

Examples

use camino::Utf8Path;

assert_eq!("foo", Utf8Path::new("foo.rs").file_stem().unwrap());
assert_eq!("foo.tar", Utf8Path::new("foo.tar.gz").file_stem().unwrap());

pub fn extension(&self) -> Option<&str>

Extracts the extension of self.file_name, if possible.

The extension is:

• None, if there is no file name;
• None, if there is no embedded .;
• None, if the file name begins with . and has no other .s within;
• Otherwise, the portion of the file name after the final .

Examples

use camino::Utf8Path;

assert_eq!("rs", Utf8Path::new("foo.rs").extension().unwrap());
assert_eq!("gz", Utf8Path::new("foo.tar.gz").extension().unwrap());

pub fn join(&self, path: impl AsRef<Utf8Path>) -> Utf8PathBuf

Creates an owned Utf8PathBuf with path adjoined to self.

See Utf8PathBuf::push for more details on what it means to adjoin a path.

Examples

use camino::{Utf8Path, Utf8PathBuf};

assert_eq!(Utf8Path::new("/etc").join("passwd"), Utf8PathBuf::from("/etc/passwd"));

pub fn join_os(&self, path: impl AsRef<Path>) -> PathBuf

Creates an owned PathBuf with path adjoined to self.

See PathBuf::push for more details on what it means to adjoin a path.

Examples

use camino::Utf8Path;
use std::path::PathBuf;

assert_eq!(Utf8Path::new("/etc").join_os("passwd"), PathBuf::from("/etc/passwd"));

pub fn with_file_name(&self, file_name: impl AsRef<str>) -> Utf8PathBuf

Creates an owned Utf8PathBuf like self but with the given file name.

See Utf8PathBuf::set_file_name for more details.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let path = Utf8Path::new("/tmp/foo.txt");
assert_eq!(path.with_file_name("bar.txt"), Utf8PathBuf::from("/tmp/bar.txt"));

let path = Utf8Path::new("/tmp");
assert_eq!(path.with_file_name("var"), Utf8PathBuf::from("/var"));

pub fn with_extension(&self, extension: impl AsRef<str>) -> Utf8PathBuf

Creates an owned Utf8PathBuf like self but with the given extension.

See Utf8PathBuf::set_extension for more details.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let path = Utf8Path::new("foo.rs");
assert_eq!(path.with_extension("txt"), Utf8PathBuf::from("foo.txt"));

let path = Utf8Path::new("foo.tar.gz");
assert_eq!(path.with_extension(""), Utf8PathBuf::from("foo.tar"));
assert_eq!(path.with_extension("xz"), Utf8PathBuf::from("foo.tar.xz"));
assert_eq!(path.with_extension("").with_extension("txt"), Utf8PathBuf::from("foo.txt"));

pub fn components(&self) -> Utf8Components<'_>

Produces an iterator over the Utf8Components of the path.

When parsing the path, there is a small amount of normalization:

• Repeated separators are ignored, so a/b and a//b both have a and b as components.

• Occurrences of . are normalized away, except if they are at the beginning of the path. For example, a/./b, a/b/, a/b/. and a/b all have a and b as components, but ./a/b starts with an additional CurDir component.

• A trailing slash is normalized away, /a/b and /a/b/ are equivalent.

Note that no other normalization takes place; in particular, a/c and a/b/../c are distinct, to account for the possibility that b is a symbolic link (so its parent isn’t a).

Examples

use camino::{Utf8Component, Utf8Path};

let mut components = Utf8Path::new("/tmp/foo.txt").components();

assert_eq!(components.next(), Some(Utf8Component::RootDir));
assert_eq!(components.next(), Some(Utf8Component::Normal("tmp")));
assert_eq!(components.next(), Some(Utf8Component::Normal("foo.txt")));
assert_eq!(components.next(), None)

pub fn iter(&self) -> Iter<'_>

Produces an iterator over the path’s components viewed as str slices.

For more information about the particulars of how the path is separated into components, see components.

Examples

use camino::Utf8Path;

let mut it = Utf8Path::new("/tmp/foo.txt").iter();
assert_eq!(it.next(), Some(std::path::MAIN_SEPARATOR.to_string().as_str()));
assert_eq!(it.next(), Some("tmp"));
assert_eq!(it.next(), Some("foo.txt"));
assert_eq!(it.next(), None)

pub fn metadata(&self) -> Result<Metadata, Error>

Queries the file system to get information about a file, directory, etc.

This function will traverse symbolic links to query information about the destination file.

This is an alias to fs::metadata.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/Minas/tirith");
let metadata = path.metadata().expect("metadata call failed");
println!("{:?}", metadata.file_type());

pub fn symlink_metadata(&self) -> Result<Metadata, Error>

Queries the metadata about a file without following symlinks.

This is an alias to fs::symlink_metadata.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/Minas/tirith");
let metadata = path.symlink_metadata().expect("symlink_metadata call failed");
println!("{:?}", metadata.file_type());

pub fn canonicalize(&self) -> Result<PathBuf, Error>

Returns the canonical, absolute form of the path with all intermediate components normalized and symbolic links resolved.

This returns a PathBuf because even if a symlink is valid Unicode, its target may not be. For a version that returns a Utf8PathBuf, see canonicalize_utf8.

This is an alias to fs::canonicalize.

Examples

use camino::Utf8Path;
use std::path::PathBuf;

let path = Utf8Path::new("/foo/test/../test/bar.rs");
assert_eq!(path.canonicalize().unwrap(), PathBuf::from("/foo/test/bar.rs"));

pub fn canonicalize_utf8(&self) -> Result<Utf8PathBuf, Error>

Returns the canonical, absolute form of the path with all intermediate components normalized and symbolic links resolved.

This method attempts to convert the resulting PathBuf into a Utf8PathBuf. For a version that does not attempt to do this conversion, see canonicalize.

Errors

The I/O operation may return an error: see the fs::canonicalize documentation for more.

If the resulting path is not UTF-8, an io::Error is returned with the ErrorKind set to InvalidData and the payload set to a FromPathBufError.

Examples

use camino::{Utf8Path, Utf8PathBuf};

let path = Utf8Path::new("/foo/test/../test/bar.rs");
assert_eq!(path.canonicalize_utf8().unwrap(), Utf8PathBuf::from("/foo/test/bar.rs"));

pub fn read_link(&self) -> Result<PathBuf, Error>

Reads a symbolic link, returning the file that the link points to.

This returns a PathBuf because even if a symlink is valid Unicode, its target may not be. For a version that returns a Utf8PathBuf, see read_link_utf8.

This is an alias to fs::read_link.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/laputa/sky_castle.rs");
let path_link = path.read_link().expect("read_link call failed");

pub fn read_link_utf8(&self) -> Result<Utf8PathBuf, Error>

Reads a symbolic link, returning the file that the link points to.

This method attempts to convert the resulting PathBuf into a Utf8PathBuf. For a version that does not attempt to do this conversion, see read_link.

Errors

The I/O operation may return an error: see the fs::read_link documentation for more.

If the resulting path is not UTF-8, an io::Error is returned with the ErrorKind set to InvalidData and the payload set to a FromPathBufError.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/laputa/sky_castle.rs");
let path_link = path.read_link_utf8().expect("read_link call failed");

pub fn read_dir(&self) -> Result<ReadDir, Error>

Returns an iterator over the entries within a directory.

The iterator will yield instances of io::Result<fs::DirEntry>. New errors may be encountered after an iterator is initially constructed.

This is an alias to fs::read_dir.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/laputa");
for entry in path.read_dir().expect("read_dir call failed") {
    if let Ok(entry) = entry {
        println!("{:?}", entry.path());
    }
}

pub fn read_dir_utf8(&self) -> Result<ReadDirUtf8, Error>

Returns an iterator over the entries within a directory.

The iterator will yield instances of io::Result<Utf8DirEntry>. New errors may be encountered after an iterator is initially constructed.

Errors

The I/O operation may return an error: see the fs::read_dir documentation for more.

If a directory entry is not UTF-8, an io::Error is returned with the ErrorKind set to InvalidData and the payload set to a FromPathBufError.

Examples

use camino::Utf8Path;

let path = Utf8Path::new("/laputa");
for entry in path.read_dir_utf8().expect("read_dir call failed") {
    if let Ok(entry) = entry {
        println!("{}", entry.path());
    }
}

pub fn exists(&self) -> bool

Returns true if the path points at an existing entity.

Warning: this method may be error-prone, consider using try_exists() instead! It also has a risk of introducing time-of-check to time-of-use (TOCTOU) bugs.

This function will traverse symbolic links to query information about the destination file. In case of broken symbolic links this will return false.

If you cannot access the directory containing the file, e.g., because of a permission error, this will return false.

Examples

use camino::Utf8Path;
assert!(!Utf8Path::new("does_not_exist.txt").exists());

See Also

This is a convenience function that coerces errors to false. If you want to check errors, call fs::metadata.

pub fn try_exists(&self) -> Result<bool, Error>

Returns Ok(true) if the path points at an existing entity.

This function will traverse symbolic links to query information about the destination file. In case of broken symbolic links this will return Ok(false).

As opposed to the exists() method, this one doesn’t silently ignore errors unrelated to the path not existing. (E.g. it will return Err(_) in case of permission denied on some of the parent directories.)

Note that while this avoids some pitfalls of the exists() method, it still can not prevent time-of-check to time-of-use (TOCTOU) bugs. You should only use it in scenarios where those bugs are not an issue.

Examples

use camino::Utf8Path;
assert!(!Utf8Path::new("does_not_exist.txt").try_exists().expect("Can't check existence of file does_not_exist.txt"));
assert!(Utf8Path::new("/root/secret_file.txt").try_exists().is_err());

pub fn is_file(&self) -> bool

Returns true if the path exists on disk and is pointing at a regular file.

This function will traverse symbolic links to query information about the destination file. In case of broken symbolic links this will return false.

If you cannot access the directory containing the file, e.g., because of a permission error, this will return false.

Examples

use camino::Utf8Path;
assert_eq!(Utf8Path::new("./is_a_directory/").is_file(), false);
assert_eq!(Utf8Path::new("a_file.txt").is_file(), true);

See Also

This is a convenience function that coerces errors to false. If you want to check errors, call fs::metadata and handle its Result. Then call fs::Metadata::is_file if it was Ok.

When the goal is simply to read from (or write to) the source, the most reliable way to test the source can be read (or written to) is to open it. Only using is_file can break workflows like diff <( prog_a ) on a Unix-like system for example. See fs::File::open or fs::OpenOptions::open for more information.

pub fn is_dir(&self) -> bool

Returns true if the path exists on disk and is pointing at a directory.

This function will traverse symbolic links to query information about the destination file. In case of broken symbolic links this will return false.

If you cannot access the directory containing the file, e.g., because of a permission error, this will return false.

Examples

use camino::Utf8Path;
assert_eq!(Utf8Path::new("./is_a_directory/").is_dir(), true);
assert_eq!(Utf8Path::new("a_file.txt").is_dir(), false);

This is a convenience function that coerces errors to false. If you want to check errors, call fs::metadata and handle its Result. Then call fs::Metadata::is_dir if it was Ok.

pub fn is_symlink(&self) -> bool

Returns true if the path exists on disk and is pointing at a symbolic link.

This function will not traverse symbolic links. In case of a broken symbolic link this will also return true.

If you cannot access the directory containing the file, e.g., because of a permission error, this will return false.

Examples

use camino::Utf8Path;
use std::os::unix::fs::symlink;

let link_path = Utf8Path::new("link");
symlink("/origin_does_not_exist/", link_path).unwrap();
assert_eq!(link_path.is_symlink(), true);
assert_eq!(link_path.exists(), false);
