Crate bidir_map

Bidirectional maps for Rust.

Examples

use bidir_map::{BidirMap, ByFirst, BySecond};
use std::default::Default;

let mut map = BidirMap::new();
assert_eq!(map, Default::default());

map.insert(1, "a");

assert_eq!(map.get_by_first(&1), Some(&"a"));
assert_eq!(map.get_by_first(&2), None);
assert_eq!(map.get_by_second(&"a"), Some(&1));
assert_eq!(map.get_by_second(&"b"), None);

assert_eq!(map[ByFirst(&1)], "a");
assert_eq!(map[BySecond(&"a")], 1);
// These would panic:
//   map[ByFirst(&2)];
//   map[BySecond(&"b")];
