[][src]Struct bidir_map::BySecond

pub struct BySecond<'q, Q: ?Sized + 'q>(pub &'q Q);

Wrapper type for getting second keys/values with first keys/values via Index.

Examples

use bidir_map::{BidirMap, BySecond};

let mut map = BidirMap::new();
map.insert(1, "a");
assert_eq!(map[BySecond(&"a")], 1);
assert_eq!(map[&BySecond(&"a")], 1);
