This crate provides a set of alternative #[derive] attributes for Rust.
This crate is not stable yet and the attributes might change at any time.
For now the crate only works on nightly but it uses rustc's Macros 1.1 and is meant to be usable on stable as soon as it is possible.
```rust
struct Foo { foo: u8, #[derivative(Debug="ignore")] bar: u8, }
println!("{:?}", Foo { foo: 42, bar: 1 }); // Foo { foo: 42 } ```

This is inspired from how [serde] wonderfully handles attributes.
This also takes some code and ideas from serde itself.
Some tests are directly adapted from rustc's tests.
