Macro idmap::direct_idmap

macro_rules! direct_idmap {
    ($($key : expr => $value : expr), *) => { ... };
    ($($key : expr => $value : expr,) *) => { ... };
}

Creates an DirectIdMap from a list of key-value pairs

Example

#[macro_use] extern crate idmap;
let map = direct_idmap! {
    1 => "a",
    25 => "b"
};
assert_eq!(map[1], "a");
assert_eq!(map[25], "b");
assert_eq!(map.get(26), None);
// 1 is the first key
assert_eq!(map.keys().next(), Some(&1));
