A set of alternative `derive` attributes for Rust

Derivative Continuous integration

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.

What it does

struct Foo {
    foo: u8,
    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.
