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 });

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.
