A library providing enum map providing type safe enum array. It is implemented using regular Rust arrays, so using them is as fast as using regular Rust arrays.
```rust
extern crate enum_map;
use enum_map::EnumMap;
enum Example { A, B, C, }
fn main() { let mut map = enum_map! { Example::A => 1, Example::B => 2, Example::C => 3, }; map[Example::C] = 4;
assert_eq!(map[Example::A], 1);
for (key, &value) in &map {
println!("{:?} has {} as value.", key, value);
}
} ```
