[−][src]Struct bidir_map::ByFirst
Wrapper type for getting second keys/values with first keys/values via Index
.
To assume that by-first is the "default" would be incorrect, so thus you one can wrap their indices with this and all is swell.
Examples
use bidir_map::{BidirMap, ByFirst}; let mut map = BidirMap::new(); map.insert(1, "a"); assert_eq!(map[ByFirst(&1)], "a"); assert_eq!(map[&ByFirst(&1)], "a");
