Struct TempDir 

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

A unique temporary directory, removed on drop.

Unique without a temp-dir crate: process id + a process-wide monotonic counter, so parallel tests within a run never collide. The name is kept deliberately short — jj’s op_store paths are deep, and a long prefix here can tip a nested .jj/repo/op_store/operations/<id> path over Windows’ MAX_PATH (260) limit.

Implementations

impl TempDir

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

Create %TEMP%/vcs-testkit-<tag>-<pid>-<n>. Panics when the directory cannot be created.

pub fn path(&self) -> &Path

The directory’s path.

Trait Implementations

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.
