Struct salsa::SweepStrategy

pub struct SweepStrategy { /* fields omitted */ }

The sweep strategy controls what data we will keep/discard when we do a GC-sweep. The default (SweepStrategy::default) is a no-op, use SweepStrategy::discard_outdated constructor or discard_* and sweep_* builder functions to construct useful strategies.

Methods

impl SweepStrategy

pub fn discard_outdated() -> SweepStrategy

Convenience function that discards all data not used thus far in the current revision.

Equivalent to SweepStrategy::default().discard_everything().

pub fn discard_values(self) -> SweepStrategy

Collects query values.

Query dependencies are left in the database, which allows to quickly determine if the query is up to date, and avoid recomputing dependencies.

pub fn discard_everything(self) -> SweepStrategy

Collects both values and information about dependencies.

Dependant queries will be recomputed even if all inputs to this query stay the same.

pub fn sweep_outdated(self) -> SweepStrategy

Process all keys, not verefied at the current revision.

pub fn sweep_all_revisions(self) -> SweepStrategy

Process all keys.
