Required Associated Types

type ReadOptions

Required Methods

fn get_pinned_full<K: AsRef<[u8]>>( &'a self, key: K, readopts: Option<Self::ReadOptions> ) -> Result<Option<DBPinnableSlice<'a>>, Error>

Return the value associated with a key using RocksDB’s PinnableSlice so as to avoid unnecessary memory copy.

Provided Methods

fn get_pinned<K: AsRef<[u8]>>( &'a self, key: K ) -> Result<Option<DBPinnableSlice<'a>>, Error>

Return the value associated with a key using RocksDB’s PinnableSlice so as to avoid unnecessary memory copy. Similar to get_pinned_opt but leverages default options.

fn get_pinned_opt<K: AsRef<[u8]>>( &'a self, key: K, readopts: Self::ReadOptions ) -> Result<Option<DBPinnableSlice<'a>>, Error>

Return the value associated with a key using RocksDB’s PinnableSlice so as to avoid unnecessary memory copy.
