Struct TempDir 

pub struct TempDir(/* private fields */);

A directory under the system temp directory, removed when this value is dropped — including while a panic unwinds.

let dir = TempDir::new("my-test");
std::fs::write(dir.join("key"), "secret").expect("writes");
let path = dir.path().to_path_buf();
drop(dir);
assert!(!path.exists());

Implementations

impl TempDir

pub fn new(tag: &str) -> Self

Creates a directory named after tag, unique to this call.

Panics

If the directory cannot be created — a test cannot continue without it.

pub fn path(&self) -> &Path

The directory itself.

pub fn join(&self, name: &str) -> PathBuf

A path inside it. The file need not exist.

Trait Implementations

impl Debug for TempDir

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for TempDir

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
