Struct same_file::Handle

pub struct Handle(_);

A handle to a file that can be tested for equality with other handles.

If two files are the same, then any two handles of those files will compare equal. If two files are not the same, then any two handles of those files will compare not-equal.

A handle consumes an open file resource as long as it exists.

Note that it's possible for comparing two handles to produce a false positive on some platforms. Namely, two handles can compare equal even if the two handles don't point to the same file.

Methods

impl Handle

fn from_path<P: AsRef<Path>>(p: P) -> Result<Handle>

Construct a handle from a path.

Note that the underlying File is opened in read-only mode on all platforms.

fn from_file(file: File) -> Result<Handle>

Construct a handle from a file.

fn stdin() -> Result<Handle>

Construct a handle from stdin.

fn stdout() -> Result<Handle>

Construct a handle from stdout.

fn stderr() -> Result<Handle>

Construct a handle from stderr.

fn as_file(&self) -> &File

Return a reference to the underlying file.

fn as_file_mut(&mut self) -> &mut File

Return a mutable reference to the underlying file.

fn dev(&self) -> u64

Return the underlying device number of this handle.

fn ino(&self) -> u64

Return the underlying inode number of this handle.

Trait Implementations

impl AsRawFd for Handle

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl IntoRawFd for Handle

fn into_raw_fd(self) -> RawFd

Consumes this object, returning the raw underlying file descriptor.

impl Debug for Handle

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for Handle

impl PartialEq for Handle

fn eq(&self, __arg_0: &Handle) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Handle) -> bool

This method tests for !=.
