Mara Bos 676ff77fb7 Rollup merge of #80726 - lcnr:unsize-query, r=oli-obk ... relax adt unsizing requirements Changes unsizing of structs in case the last struct field shares generic params with other adt fields which do not change. This change is currently insta stable and changes the language, so it at least requires a lang fcp. I feel like the current state is fairly unintuitive. An example for what's now allowed would be https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=6dd331d23f5c9ffc8c978175aae2e967 ```rust struct A<T, U: ?Sized>(T, B<T, U>); // previously ERR // struct A<T, U: ?Sized>(T, B<[u32; 1], U>); // ok struct B<T, U: ?Sized>(T, U); fn main() { let x = A([0; 1], B([0; 1], [0; 1])); let y: &A<[u32; 1], [u32]> = &x; assert_eq!(y.1.1.len(), 1); } ```		2021-02-05 12:25:52 +01:00
