pub fn get<K>(&self, key: K) -> Result<Option<Vec<u8>>, Error>

where K: AsRef<[u8]>,

Returns the bytes associated with a key value with default read options.

pub fn get_cf<K>( &self, cf: &impl AsColumnFamilyRef, key: K, ) -> Result<Option<Vec<u8>>, Error>

where K: AsRef<[u8]>,

Returns the bytes associated with a key value and given column family with default read options.

pub fn get_opt<K>( &self, key: K, readopts: ReadOptions, ) -> Result<Option<Vec<u8>>, Error>

where K: AsRef<[u8]>,

Returns the bytes associated with a key value and given read options.

pub fn get_cf_opt<K>( &self, cf: &impl AsColumnFamilyRef, key: K, readopts: ReadOptions, ) -> Result<Option<Vec<u8>>, Error>

where K: AsRef<[u8]>,

Returns the bytes associated with a key value, given column family and read options.

pub fn get_pinned<K>( &self, key: K, ) -> Result<Option<DBPinnableSlice<'_>>, Error>

where K: AsRef<[u8]>,

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.

pub fn get_pinned_cf<K>( &self, cf: &impl AsColumnFamilyRef, key: K, ) -> Result<Option<DBPinnableSlice<'_>>, Error>

where K: AsRef<[u8]>,

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

pub fn get_pinned_opt<K>( &self, key: K, readopts: ReadOptions, ) -> Result<Option<DBPinnableSlice<'_>>, Error>

where K: AsRef<[u8]>,

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

pub fn get_pinned_cf_opt<K>( &self, cf: &impl AsColumnFamilyRef, key: K, readopts: ReadOptions, ) -> Result<Option<DBPinnableSlice<'_>>, Error>

where K: AsRef<[u8]>,

Return the value associated with a key using RocksDB’s PinnableSlice so as to avoid unnecessary memory copy. Similar to get_pinned_opt but allows specifying ColumnFamily.

pub fn multi_get<K, I>(&self, keys: I) -> Vec<Result<Option<Vec<u8>>, Error>>

where K: AsRef<[u8]>, I: IntoIterator<Item = K>,
