Implementations§

source§

impl<T> RefreshIntrospectionState<T>

source

fn row_for_collection(&self, collection_id: GlobalId) -> Row

Return a Row reflecting the current refresh introspection state.

source§

impl<T: ComputeControllerTimestamp> RefreshIntrospectionState<T>

source

fn new( refresh_schedule: RefreshSchedule, initial_as_of: Antichain<T>, upper: &Antichain<T>, ) -> Self

Construct a new RefreshIntrospectionState, and apply an initial frontier_update() at the upper.

source

fn frontier_update(&mut self, write_frontier: &Antichain<T>)

Should be called whenever the write frontier of the collection advances. It updates the state that should be recorded in introspection relations, but doesn’t send the updates yet.
