# Function std::env::temp_dir 1.0.0 [−] [src]

    pub fn temp_dir() -> PathBuf

Returns the path of a temporary directory.

On Unix, returns the value of the `TMPDIR` environment variable if it is set, otherwise for non-Android it returns `/tmp`. If Android, since there is no global temporary folder (it is usually allocated per-app), it returns `/data/local/tmp`.

On Windows, returns the value of, in order, the `TMP`, `TEMP`, `USERPROFILE` environment variable if any are set and not the empty string. Otherwise, `temp_dir` returns the path of the Windows directory. This behavior is identical to that of `GetTempPath`, which this function uses internally.

fn main() { use std::env; use std::fs::File; fn foo() -> std::io::Result<()> { let mut dir = env::temp_dir(); dir.push("foo.txt"); let f = try!(File::create(dir)); Ok(()) } }

    use std::env;
    use std::fs::File;

    let mut dir = env::temp_dir();
    dir.push("foo.txt");

    let f = try!(File::create(dir));

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
