Enumoid

This crate is a Rust library which provides containers indexed by enums.

Dependency

toml [dependencies] enumoid = "0.2"

Using Enumoid

The Enumoid trait provides a mapping between the values which inhabit a type and the integers between 0 and n, where n is the number of distinct values. This is used to provide several container data structures backed by fixed-size arrays and generic over an Enumoid index of type T.

For example, a total mapping:

rust let mut map = EnumMap::<FooBar, String>::new(); map[FooBar::Foo] = "Hello".to_string();

The Enumoid trait can be implemented for any enum type using the Enumoid derive macro.

```rust

[derive(Enumoid)]

enum FooBar { Foo, Bar } ```
