Trait Implementations

impl Record for IndexKey

fn compare(&self, db: &DB, data: &[u8]) -> Ordering

Compare record with stored bytes.

fn save(&self, _data: &mut [u8])

Save record as bytes.

fn key(&self, _db: &DB, data: &[u8]) -> Box<dyn Record>

Load key from bytes ( to store in parent page ).

fn drop_key(&self, _db: &DB, _data: &[u8])

Drop parent key ( may need to delete codes ).
