Struct std::old_io::TempDirUnstable

pub struct TempDir {
    // some fields omitted
}

A wrapper for a path to temporary directory implementing automatic scope-based deletion.

Examples

fn main() { use std::old_io::TempDir; { // create a temporary directory let tmpdir = match TempDir::new("myprefix") { Ok(dir) => dir, Err(e) => panic!("couldn't create temporary directory: {}", e) }; // get the path of the temporary directory without affecting the wrapper let tmppath = tmpdir.path(); println!("The path of temporary directory is {}", tmppath.display()); // the temporary directory is automatically removed when tmpdir goes // out of scope at the end of the block } { // create a temporary directory, this time using a custom path let tmpdir = match TempDir::new_in(&Path::new("/tmp/best/custom/path"), "myprefix") { Ok(dir) => dir, Err(e) => panic!("couldn't create temporary directory: {}", e) }; // get the path of the temporary directory and disable automatic deletion in the wrapper let tmppath = tmpdir.into_inner(); println!("The path of the not-so-temporary directory is {}", tmppath.display()); // the temporary directory is not removed here // because the directory is detached from the wrapper } { // create a temporary directory let tmpdir = match TempDir::new("myprefix") { Ok(dir) => dir, Err(e) => panic!("couldn't create temporary directory: {}", e) }; // close the temporary directory manually and check the result match tmpdir.close() { Ok(_) => println!("success!"), Err(e) => panic!("couldn't remove temporary directory: {}", e) }; } }

use std::old_io::TempDir;

{
    // create a temporary directory
    let tmpdir = match TempDir::new("myprefix") {
        Ok(dir) => dir,
        Err(e) => panic!("couldn't create temporary directory: {}", e)
    };

    // get the path of the temporary directory without affecting the wrapper
    let tmppath = tmpdir.path();

    println!("The path of temporary directory is {}", tmppath.display());

    // the temporary directory is automatically removed when tmpdir goes
    // out of scope at the end of the block
}
{
    // create a temporary directory, this time using a custom path
    let tmpdir = match TempDir::new_in(&Path::new("/tmp/best/custom/path"), "myprefix") {
        Ok(dir) => dir,
        Err(e) => panic!("couldn't create temporary directory: {}", e)
    };

    // get the path of the temporary directory and disable automatic deletion in the wrapper
    let tmppath = tmpdir.into_inner();

    println!("The path of the not-so-temporary directory is {}", tmppath.display());

    // the temporary directory is not removed here
    // because the directory is detached from the wrapper
}
{
    // create a temporary directory
    let tmpdir = match TempDir::new("myprefix") {
        Ok(dir) => dir,
        Err(e) => panic!("couldn't create temporary directory: {}", e)
    };

    // close the temporary directory manually and check the result
    match tmpdir.close() {
        Ok(_) => println!("success!"),
        Err(e) => panic!("couldn't remove temporary directory: {}", e)
    };
}

Methods

impl TempDir

fn new_in(tmpdir: &Path, prefix: &str) -> IoResult<TempDir>

Attempts to make a temporary directory inside of tmpdir whose name will have the prefix prefix. The directory will be automatically deleted once the returned wrapper is destroyed.

If no directory can be created, Err is returned.

fn new(prefix: &str) -> IoResult<TempDir>

Attempts to make a temporary directory inside of os::tmpdir() whose name will have the prefix prefix. The directory will be automatically deleted once the returned wrapper is destroyed.

If no directory can be created, Err is returned.

fn into_inner(self) -> Path

Unwrap the wrapped std::path::Path from the TempDir wrapper. This discards the wrapper so that the automatic deletion of the temporary directory is prevented.

fn path<'a>(&'a self) -> &'a Path

Access the wrapped std::path::Path to the temporary directory.

fn close(self) -> IoResult<()>

Close and remove the temporary directory

Although TempDir removes the directory on drop, in the destructor any errors are ignored. To detect errors cleaning up the temporary directory, call close instead.
