Required Methods§

Source

fn get_pinned_cf_full<K: AsRef<[u8]>>( &'a self, cf: Option<Self::ColumnFamily>, 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§

Source

fn get_pinned_cf<K: AsRef<[u8]>>( &'a self, cf: Self::ColumnFamily, 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.

Source

fn get_pinned_cf_opt<K: AsRef<[u8]>>( &'a self, cf: Self::ColumnFamily, 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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
