fn get(&self, key: &[u8]) -> Option<Vec<u8>>[src]
fn index_get(
&self,
index: &str,
key: &[u8]
) -> Result<Option<Vec<u8>>, DatabaseError>[src]
&self,
index: &str,
key: &[u8]
) -> Result<Option<Vec<u8>>, DatabaseError>
fn cursor(&self) -> Result<DatabaseCursor, DatabaseError>[src]
Returns a cursor against the main database. The cursor iterates over the entries in the natural key order.
fn index_cursor(&self, index: &str) -> Result<DatabaseCursor, DatabaseError>[src]
Returns a cursor against the given index. The cursor iterates over the entries in the index's natural key order.
fn count(&self) -> Result<usize, DatabaseError>[src]
Returns the number of entries in the main database.
fn index_count(&self, index: &str) -> Result<usize, DatabaseError>[src]
Returns the number of entries in the given index.
