Rollup merge of #94457 - jhpratt:stabilize-derive_default_enum, r=davidtwco
Stabilize `derive_default_enum` This stabilizes `#![feature(derive_default_enum)]`, as proposed in [RFC 3107](https://github.com/rust-lang/rfcs/pull/3107) and tracked in #87517. In short, it permits you to `#[derive(Default)]` on `enum`s, indicating what the default should be by placing a `#[default]` attribute on the desired variant (which must be a unit variant in the interest of forward compatibility). ```````@rustbot``````` label +S-waiting-on-review +T-lang
