This crate provides a set of alternative customizable #[derive] attributes for Rust.
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.
#[derive(Derivative)]
#[derivative(Debug)]
struct Foo {
foo: u8,
#[derivative(Debug="ignore")]
bar: u8,
}
// Prints `Foo { foo: 42 }`
println!("{:?}", Foo { foo: 42, bar: 1 });Check the documentation for more!

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.
