:
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")];
