enum-map

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.

This crate follows the "N minus two" MSRV policy. This means that it supports the current Rust release, as well as the two before that.

Examples

#[macro_use]
extern crate enum_map;

use enum_map::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);
    }
}
