Expand description

Checkpointed local cache invalidation, including namespace enumeration.

Required Methods§

Source

fn invalidate<'a>( &'a self, request: &'a Request, cursor: u32, budget: &'a SliceBudget, ) -> BoxFuture<'a, Result<Option<u32>, StoreError>>

Charge enumeration and deletes before doing them. None means complete; Some(cursor) resumes at the next operation in another alarm.

Provided Methods§

Source

fn invalidate_checkpoint<'a>( &'a self, request: &'a Request, checkpoint: &'a [u8], budget: &'a SliceBudget, ) -> BoxFuture<'a, Result<Option<Vec<u8>>, StoreError>>

Opaque durable position for catalog traversal; legacy local adapters use a u32.

Dyn Compatibility§

This trait is dyn compatible.

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