tempdir

A Rust library for creating a temporary directory and deleting its entire contents when the directory is dropped.

Documentation

Usage

Add this to your Cargo.toml:

[dependencies]
tempdir = "0.3"

and this to your crate root:

extern crate tempdir;

Example

This sample method does the following:

1. Create a temporary directory in the default location with the given prefix.
2. Determine a file path in the directory and print it out.
3. Create a file inside the temp folder.
4. Write to the file and sync it to disk.
5. Close the directory, deleting the contents in the process.

use std::io::{self, Write};
use std::fs::File;
use tempdir::TempDir;

fn write_temp_folder_with_files() -> io::Result<()> {
    let dir = TempDir::new("my_directory_prefix")?;
    let file_path = dir.path().join("foo.txt");
    println!("{:?}", file_path);

    let mut f = File::create(file_path)?;
    f.write_all(b"Hello, world!")?;
    f.sync_all()?;
    dir.close()?;

    Ok(())
}

Note: Closing the directory is actually optional, as it would be done on drop. The benefit of closing here is that it allows possible errors to be handled.
