pub struct BTreeBimap<L: Ord, R: Ord> { /* private fields */ }
Expand description

双方向連想配列。

$k\mapsto v$ ではなく、全単射となるように $k_l\mapsto k_r$ と $k_r\mapsto k_l$ を管理する。

Examples

use nekolib::ds::BTreeBimap;

let mut bimap = BTreeBimap::new();

bimap.insert(1, 'a');
bimap.insert(2, 'b');
bimap.insert(3, 'c');

bimap.insert(1, 'b');
assert_eq!(bimap.len(), 2); // {1: 'b', 3, 'c'}

bimap.remove_left(&1);
bimap.remove_right(&'c');
assert!(bimap.is_empty());
