Structs

DBTransaction	Write transaction. Batches a sequence of put/delete operations for efficiency.
IoStats	Statistic for the span period

Enums

DBOp	Database operation.
IoStatsKind	Statistic kind to query.

Constants

PREFIX_LEN

Traits

KeyValueDB

Generic key-value database.

Functions

end_prefix

For a given start prefix (inclusive), returns the correct end prefix (non-inclusive). This assumes the key bytes are ordered in lexicographical order. Since key length is not limited, for some case we return None because there is no bounded limit (every keys in the serie [], [255], [255, 255] …).

Type Definitions

DBKey	Database keys.
DBValue	Database value.
