Expand description
Traits for reading and writing from databases.
Transact operates on key-value entries at the database level, where both keys and values are opaque bytes.
§Readers and Writers
Both the DatabsaeReader and DatabaseWriter traits imply that the underlying database implementation maintains transactional consistency throughout their lifetimes. For example, while a cursor on a DatabaseReader is in use, any changes to the underlying data should not alter the iteration of the reader.
Changes to the underlying database are rendered via the DatabaseWriter’s commit method.
