Function std::env::temp_dirUnstable

pub fn temp_dir() -> Path

Returns the path to 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), we return '/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, tmpdir returns the path to the Windows directory.
