Struct mz_persist_client :: internal :: gc :: GcRollups Copy item path

impl GcRollups

fn new( rollups_lte_seqno_since: Vec<(SeqNo, PartialRollupKey)>, gc_req: &GcReq, ) -> Self

fn contains_seqno(&self, seqno: &SeqNo) -> bool

fn truncate_seqnos(&self) -> impl Iterator<Item = SeqNo> + '_

Returns the seqnos we can safely truncate state to when performing incremental GC (all rollups with seqnos <= seqno_since).

fn rollups_to_remove_from_state(&self) -> &[(SeqNo, PartialRollupKey)]

Returns the rollups we can safely remove from state (all rollups < than the latest rollup <= seqno_since).

See the full explanation in crate::internal::state_versions::StateVersions for how this is derived.
