Temporary directories of files.
The TempDir
type creates a directory on the file system that
is deleted once it goes out of scope. At construction, the
TempDir
creates a new directory with a randomly generated name
and a prefix of your choosing.
§Examples
extern crate tempdir;
use std::fs::File;
use std::io::{self, Write};
use tempdir::TempDir;
fn main() {
if let Err(_) = run() {
::std::process::exit(1);
}
}
fn run() -> Result<(), io::Error> {
// Create a directory inside of `std::env::temp_dir()`, named with
// the prefix "example".
let tmp_dir = TempDir::new("example")?;
let file_path = tmp_dir.path().join("my-temporary-note.txt");
let mut tmp_file = File::create(file_path)?;
writeln!(tmp_file, "Brian was here. Briefly.")?;
// By closing the `TempDir` explicitly, we can check that it has
// been deleted successfully. If we don't close it explicitly,
// the directory will still be deleted when `tmp_dir` goes out
// of scope, but we won't know whether deleting the directory
// succeeded.
drop(tmp_file);
tmp_dir.close()?;
Ok(())
