Struct ScratchRegistry 

pub struct ScratchRegistry { /* private fields */ }

Owns the temp paths minted during one interpreter run and removes them on drop.

Holds PathBufs rather than open handles deliberately: the Lisp side needs a path string it can pass to subprocesses, and a script legitimately creates, removes, and recreates files underneath a scratch dir. Ownership here is of the path’s lifetime, not of a file descriptor.

Implementations

impl ScratchRegistry

pub fn dir(&mut self) -> Result<PathBuf>

Mint an owned scratch DIRECTORY and return its path.

pub fn file(&mut self) -> Result<PathBuf>

Mint an owned scratch FILE (created empty) and return its path.

pub fn len(&self) -> usize

Number of live scratch entries. Exposed for tests.

pub fn is_empty(&self) -> bool

Whether the registry currently owns nothing.

Trait Implementations

impl Debug for ScratchRegistry

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

Formats the value using the given formatter.

impl Default for ScratchRegistry

fn default() -> ScratchRegistry

Returns the “default value” for a type.

impl Drop for ScratchRegistry

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.
