2 directional hashmaps in rust
This crate aims to provide a data structure that can store a 1:1 relation between two different types. This data structure also provides constant time lookup within this relation - in either direction.
```rust use isomorphism::BiMap;
fn main() { let mut map = BiMap::new(); map.insert("Hello", "World");
assert_eq!(map.get_left("Hello"), Some(&"World"));
assert_eq!(map.get_right("World"), Some(&"Hello"));
} ```
