This allows writing the following function signatures: ```rust fn f0() -> impl Fn() -> impl Trait; fn f3() -> &'static dyn Fn() -> impl Trait; ``` These signatures were already allowed for common traits and associated types, there is no reason why `Fn*` traits should be special in this regard.

…errors Allow `impl Fn() -> impl Trait` in return position _This was originally proposed as part of rust-lang#93082 which was [closed](rust-lang#93082 (comment)) due to allowing `impl Fn() -> impl Trait` in argument position._ This allows writing the following function signatures: ```rust fn f0() -> impl Fn() -> impl Trait; fn f3() -> &'static dyn Fn() -> impl Trait; ``` These signatures were already allowed for common traits and associated types, there is no reason why `Fn*` traits should be special in this regard. `impl Trait` in both `f0` and `f3` means "new existential type", just like with `-> impl Iterator<Item = impl Trait>` and such. Arrow in `impl Fn() ->` is right-associative and binds from right to left, it's tested by [this test](https://github.com/WaffleLapkin/rust/blob/a819fecb8dea438fc70488ddec30a61e52942672/src/test/ui/impl-trait/impl_fn_associativity.rs). There even is a test that `f0` compiles: https://github.com/rust-lang/rust/blob/2f004d2d401682e553af3984ebd9a3976885e752/src/test/ui/impl-trait/nested_impl_trait.rs#L25-L28 But it was changed in [PR 48084 (lines)](https://github.com/rust-lang/rust/pull/48084/files#diff-ccecca938872d65ffe8cd1c3ef1956e309fac83bcda547d8b16b89257e53a437R37) to test the opposite, probably unintentionally given [PR 48084 (lines)](https://github.com/rust-lang/rust/pull/48084/files#diff-5a02f1ed43debed1fd24f7aad72490064f795b9420f15d847bac822aa4621a1cR476-R477). r? `@nikomatsakis` ---- This limitation is especially annoying with async code, since it forces one to write this: ```rust trait AsyncFn3<A, B, C>: Fn(A, B, C) -> <Self as AsyncFn3<A, B, C>>::Future { type Future: Future<Output = Self::Out>; type Out; } impl<A, B, C, Fut, F> AsyncFn3<A, B, C> for F where F: Fn(A, B, C) -> Fut, Fut: Future, { type Future = Fut; type Out = Fut::Output; } fn async_closure() -> impl AsyncFn3<i32, i32, i32, Out = u32> { |a, b, c| async move { (a + b + c) as u32 } } ``` Instead of: ```rust fn async_closure() -> impl Fn(i32, i32, i32) -> impl Future<Output = u32> { |a, b, c| async move { (a + b + c) as u32 } } ```

Fake capture closures if typeck results are empty This ICE happens because `closure_min_captures` is empty, the reason it's empty is with the 2021 edition `enable_precise_capture` is set to true, which makes it so that we can't fake capture any information because that result of the `unwrap` is none hence the ICE. Other solution is editing [maybe_read_scrutinee](https://doc.rust-lang.org/nightly/nightly-rustc/src/rustc_typeck/expr_use_visitor.rs.html#453-463) to this since empty slice contains no sub patterns. Fixes rust-lang#93242 ```rust PatKind::Slice(_, ref slice, _) => { if slice.is_none(){ need_to_be_read = true; } } // instead of PatKind::Or(_) | PatKind::Box(_) | PatKind::Slice(..) | PatKind::Ref(..) | PatKind::Wild => {} ```

Prevent foreign Rust exceptions from being caught Fix rust-lang#102715 Use the address of a static variable (which is guaranteed to be unique per copy of std) to tell apart if a Rust exception comes from local or foreign Rust code, and abort for the latter.

…r=oli-obk Make `CStr::from_ptr` `const`. Should be included in rust-lang#101719. cc `@WaffleLapkin`

…, r=compiler-errors Add test for issue 98634 Fixes rust-lang#98634

Note scope of TAIT more accurately This maybe explains why the person was confused in rust-lang#101897, since we say "same module" but really should've said "same impl". r? `@oli-obk`
