API

async copy(key,destKey,?overwrite,?version,?ifVersion) - returns boolean

Copies the value at key to destKey with the optional version. If overwrite is true and destKey already exists, it will be overwritten. Otherwise, an Error EEXIST: ${key} is thrown. If key does not exist an Error ENOENT: ${key} is thrown. If optional ifVersion does not match current version, the function returns false.

withExtensions(db:lmdbDatabase,extenstions:object) - returns lmdbDatabase`

Extends an LMDB database and any child databases it opens to have the extensions provided as well as any child databases it opens. This utility is common to other lmdb extensions like lmdb-patch, lmdb-move.

Automatically adds copy.
