amap

Simple array initialization macro.

Ever wanted to create a const HashMap<usize, T>, and started thinking, wouldn't it be nice if this was a array?

No?

Well now you can! Its as simple as

rust amap! { 4 => 56, 2 => 32, } // creates a [Option<i32>; 5] for all your indexing needs

Think it would be too much boilerplate to have multiple keys for one value?

Patterns got you covered!

rust amap! { 0..=4 => 2, 5 | 6 => 3, }

Want to put it in a constant? No problem!

It's just a array!

rust const ID_MAP: [Option<i32>; 6] = amap! { 5 => 6, 2 => 1, }
