Enum TryFrom

A crate to derive the TryFrom trait on enums using procedural macros.

Expect frequent breakage for now.

Documentation

This adds the ability to #[derive(TryFromPrimitive)], which in combination with one (well zero, but that's not useful) or more #[FromPrimitiveType="type"] attributes lets you automatically derive TryFrom<type> for enum types.

Detailed documentation can be generated with cargo doc.

lib.rs:

This crate contains macros for deriving useful traits on C-like enums
