Structs

DBTransaction

Write transaction. Batches a sequence of put/delete operations for efficiency.

Enums

Database operation.

IoStatsKind

Statistic kind to query.

Constants

PREFIX_LEN

Required length of prefixes.

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 Aliases

DBKey

Database keys.

DBKeyValue

A tuple holding key and value data, used in the iterator item type.

DBValue

Database value.
