derivation

Deriving traits for C-like enums using macro 1.1.

This crate makes 2 traits derivable for C-like enums, namely Variants and FromStr. The first one could be derived for enums to transform it into a list of variants, and the second make parsing from &str to an enum easy as a piece of cake.

Supports Rust 1.15 and above.

How to use:

1. Add these 2 crate as dependencies in your Cargo.toml

   [dependencies]
   
   derivation = "^0.1"
   enum_variants = "^1.0"

2. Now import this crate in your source code at the top of your crate

   #[macro_use]
   extern crate derivation;

3. The trait Variants has only one method: fn variants() -> Vec<Self>; which should return the list of all variants. Import it when you need to derive it:

   extern crate enum_variants;
   
   use enum_variants::Variants;

4. Derive FromStr or Variants like you do with other traits:

   #[derive(FromStr, Variants)]
   enum Enum {
       /* ... */
   }

Notice that only C-like (unitary) enums are supported!
