// This test checks the code generated for all[*] the builtin derivable traits
// on a variety of structs and enums. It protects against accidental changes to
// the generated code, and makes deliberate changes to the generated code
// easier to review.
//
// [*] It excludes `Copy` in some cases, because that changes the code
// generated for `Clone`.
//
// [*] It excludes `RustcEncodable` and `RustDecodable`, which are obsolete and
// also require the `rustc_serialize` crate.
