Available on crate features std and ua only.

Deterministic bottom-k sampling independent of transport and emulation randomness.

Structs

ObservationReservoir

Capacity bounds entry count. The value interner independently bounds payload bytes. Counting and duplicate admission belong to the enclosing ingestion transaction.

ReservoirEntry

The referenced canonical value contains the whole slot or joint observation. Joint values are never reconstructed from independently sampled slots.

Enums

ReservoirUpdate

Apply insertion/removal to the value interner in the same counting transaction.
