Struct TrustedScratch 

pub struct TrustedScratch { /* private fields */ }

Validated trusted-service scratch root. It owns an open descriptor so the validated root remains the authority for attempt creation.

Implementations

impl TrustedScratch

pub fn open<'a>( root: &Path, filesystem_lake_locations: impl IntoIterator<Item = &'a Path>, ) -> Result<Self, ScratchError>

pub fn create_session_attempt( &self, identifier: ScratchAttemptId, ) -> Result<ScratchAttempt, ScratchError>

Session-local DuckDB spill is distinct from durable Dataset attempt scratch. A retained OS lease lets a restarted runtime reap only stopped Sessions.

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

Reaps abandoned Session spill only. Dataset attempt directories have no Session marker and must use shared durable attempt recovery, even when no public operation exists. A live lease always prevents deletion.

pub fn create_attempt( &self, identifier: ScratchAttemptId, ) -> Result<ScratchAttempt, ScratchError>

Trait Implementations

impl Debug for TrustedScratch

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

Formats the value using the given formatter.
