tempdir
=======
A Rust library for creating a temporary directory and deleting its entire
contents when the directory is dropped.
[![Build Status](https://travis-ci.org/rust-lang-nursery/tempdir.svg?branch=master)](https://travis-ci.org/rust-lang-nursery/tempdir)
[![Build status](https://ci.appveyor.com/api/projects/status/2mp24396db5t4hul/branch/master?svg=true)](https://ci.appveyor.com/project/rust-lang-libs/tempdir/branch/master)
[Documentation](https://doc.rust-lang.org/tempdir)
## Deprecation Note
The `tempdir` crate is being merged into [`tempfile`](https://github.com/Stebalien/tempfile). Please see [this issue](https://github.com/Stebalien/tempfile/issues/43) to track progress and 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.

///
/// The default constructor, [`TempDir::new`], creates directories in

/// can be configured to manage a temporary directory in any location

/// standard [`std::fs`] file system operations on its [`Path`],
/// which can be retrieved with [`TempDir::path`]. Once the `TempDir`
/// value is dropped, the directory at the path will be deleted, along
/// with any files and directories it contains. It is your responsibility
/// to ensure that no further file system operations are attempted
/// inside the temporary directory once it has been deleted.
///
/// Various platform-specific conditions may cause `TempDir` to fail
/// to delete the underlying directory. It's important to ensure that
/// handles (like [`File`] and [`ReadDir`]) to files inside the
/// directory are dropped before the `TempDir` goes out of scope. The
/// `TempDir` destructor will silently ignore any errors in deleting
/// the directory; to instead handle errors call [`TempDir::close`].
///
/// Note that if the program exits before the `TempDir` destructor is
