This crate provides a set of alternative `#[derive]` attributes for Rust.

## [Documentation][documentation]
## Stability

This crate is now stable and usable on rustc stable too!

Note that you need *rustc 1.15 or later*.

## What it does

```rust
#[derive(Derivative)]
#[derivative(Debug)]
struct Foo {
    foo: u8,
    #[derivative(Debug="ignore")]
    bar: u8,
}

println!("{:?}", Foo { foo: 42, bar: 1 }); // Foo { foo: 42 }
```

Check the [documentation] for more!

at your option.

## Acknowledgements

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.
