Trait lmdb_rs::core::IterateCursor [] [src]

pub trait IterateCursor {
    fn init_cursor<'a, 'b: 'a>(&'a self, cursor: &mut Cursor<'b>) -> bool;
    fn move_to_next<'iter, 'cursor: 'iter>(&'iter self,
                                           cursor: &'cursor mut Cursor<'cursor>)
                                           -> bool; fn get_size_hint(&self, _cursor: &Cursor) -> (usize, Option<usize>) { ... } }

Allows the cration of custom cursor iteration behaviours.

Required Methods

Returns true if initialization successful, for example that the key exists.

Returns true if there is still data and iterator is in correct range

Provided Methods

Returns size hint considering current state of cursor
