Crate enum_map

An enum mapping type.

It is implemented using an array type, so using it is as fast as using Rust arrays.

Examples

use enum_map::{enum_map, Enum, EnumMap};

#[derive(Debug, Enum)]
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);
    }
}
