Function std::env::temp_dir 1.0.0[−][src]
pub fn temp_dir() -> PathBufExpand description
Returns the path of a temporary directory.
The temporary directory may be shared among users, or between processes with different privileges; thus, the creation of any files or directories in the temporary directory must use a secure method to create a uniquely named file. Creating a file or directory with a fixed or predictable name may result in “insecure temporary file” security vulnerabilities. Consider using a crate that securely creates temporary files or directories.
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.
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.
