Expand description

Host-scheduled retention and garbage-collection capability over settled state.

Required Methods§

Source

fn tombstone_nodes<'life0, 'life1, 'async_trait>( &'life0 self, ids: &'life1 [String], ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Mark graph nodes as tombstoned so reads exclude them until vacuum physically removes them.

Source

fn vacuum<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<VacuumReport, StoreError>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

Physically delete tombstoned graph-node rows and prune terminal pending-turn-input evidence rows. See VacuumReport.

Source

fn gc_unreachable<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<GcReport, StoreError>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

Delete blobs no longer reachable from any retained root.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
