Trait leveldb::database::iterator::Iterable

pub trait Iterable<'a, K: Key + 'a> {
    fn iter(&'a self, options: ReadOptions<'a, K>) -> Iterator<K>;
    fn keys_iter(&'a self, options: ReadOptions<'a, K>) -> KeyIterator<K>;
    fn value_iter(&'a self, options: ReadOptions<'a, K>) -> ValueIterator<K>;
}

A trait to allow access to the three main iteration styles of leveldb.
