pub fn tempdir() -> Result<TempDir>Expand description
Create a new temporary directory.
The tempdir function creates a directory in the file system
and returns a TempDir.
The directory will be automatically deleted when the TempDirs
destructor is run.
§Resource Leaking
See the resource leaking docs on TempDir.
§Errors
If the directory can not be created, Err is returned.
§Examples
use tempfile::tempdir;
use std::fs::File;
use std::io::{self, Write};
// Create a directory inside of `std::env::temp_dir()`
let tmp_dir = tempdir()?;
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.")?;
// `tmp_dir` goes out of scope, the directory as well as
// `tmp_file` will be deleted here.
drop(tmp_file);
tmp_dir.close()?;
