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

## [Documentation][documentation]

## Stability

This crate is stable and follows semver. It requires *rustc 1.34 or later* and changing the minimal rustc version will be considered a semver breaking change.

## What it does

```rust

#[derive(Derivative)]

#[derivative(Debug)]

struct Foo {

    foo: u8,

    #[derivative(Debug="ignore")]

    bar: u8,

}

// Prints `Foo { foo: 42 }`

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

```

## 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.
