IndexedMap works like a Map but has a secondary index

IndexedSnapshotMap works like a SnapshotMap but has a secondary index

Item stores one typed item at the given key. This is an analog of Singleton. It functions just as Path but doesn’t ue a Vec and thus has a const fn constructor.

Map

MultiIndex

MultiIndex stores (namespace, index_name, idx_value, pk) -> b“pk_len“. Allows many values per index, and references pk. The associated primary key value is stored in the main (pk_namespace) map, which stores (namespace, pk_namespace, pk) -> value.

Path

Prefix

SnapshotItem

Item that maintains a snapshot of one or more checkpoints. We can query historical data as well as current state. What data is snapshotted depends on the Strategy.

SnapshotMap

Map that maintains a snapshots of one or more checkpoints. We can query historical data as well as current state. What data is snapshotted depends on the Strategy.

UniqueIndex

UniqueIndex stores (namespace, index_name, idx_value) -> {key, value} Allows one value per index (i.e. unique) and copies pk and data The optional PK type defines the type of Primary Key deserialization.

Enums

Bound

Bound is used to defines the two ends of a range, more explicit than Option None means that we don’t limit that side of the range at all. Include means we use the given bytes as a limit and include anything at that exact key Exclude means we use the given bytes as a limit and exclude anything at that exact key
