Matthias Krüger 90dd7c03af Rollup merge of #89359 - fee1-dead:const-it, r=oli-obk ... Various fixes for const_trait_impl A few problems I found while making `Iterator` easier to const-implement. 1. More generous `~const Drop` check. We check for nested fields with caller bounds. For example, an ADT type with fields of types `A`, `B`, `C`, check if all of them are either: - Bounded (`A: ~const Drop`, `B: Copy`) - Known to be able to destruct at compile time (`C = i32`, `struct C(i32)`, `C = some_fn`) 2. Don't treat trait functions marked with `#[default_method_body_is_const]` as stable const fns when checking `const_for` and `const_try` feature gates. I think anyone can review this, so no r? this time.		2021-11-25 15:05:35 +01:00
