Struct ScratchAttempt 

pub struct ScratchAttempt { /* private fields */ }

One exclusively-created private attempt directory.

Implementations

impl ScratchAttempt

pub fn create_dataset_attempt( &self, authority: &mut dyn DatasetOutputAuthority, ) -> Result<Self, LakeError>

Creates output-owned scratch using the durable private attempt identity.

pub fn cleanup_dataset_attempt( &self, authority: &mut dyn DatasetOutputAuthority, ) -> Result<(), LakeError>

Reconciles only the recorded attempt under this retained configured root. Executor exclusion and metadata outcome must have been claimed first.

pub fn create_child( &self, identifier: ScratchAttemptId, ) -> Result<Self, ScratchError>

Creates an exclusive child attempt under this retained scratch capability.

pub fn path(&self) -> &Path

Restricted trusted-adapter path; callers must not serialize or project it.

pub fn cleanup(&self) -> Result<(), ScratchError>

Deletes the complete attempt tree without following child symlinks. Missing attempts are already clean and therefore succeed.

Trait Implementations

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

Formats the value using the given formatter.

impl Drop for ScratchAttempt

fn drop(&mut self)

Executes the destructor for this type.
