A Rust library for creating a temporary directory and deleting its entire

contents when the directory is dropped.

[Documentation](https://doc.rust-lang.org/tempdir)



## Deprecation Note



The `tempdir` crate is being merged into [`tempfile`](https://github.com/Stebalien/tempfile) and is available in `3.x`. Please direct new issues and pull requests to `tempfile`.



## Usage



Add this to your `Cargo.toml`:



```toml

[dependencies]

tempdir = "0.3"

```



and this to your crate root:



```rust

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.



```rust

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.
