Rollup merge of #58553 - scottmcm:more-ihle, r=Centril

2019-02-20T03:59:10+00:00

Use more impl header lifetime elision Inspired by seeing explicit lifetimes on these two: - https://doc.rust-lang.org/nightly/std/slice/struct.Iter.html#impl-FusedIterator - https://doc.rust-lang.org/nightly/std/primitive.u32.html#impl-Not And a follow-up to https://github.com/rust-lang/rust/pull/54687, that started using IHLE in libcore. Most of the changes in here fall into two big categories: - Removing lifetimes from common traits that can essentially never user a lifetime from an input (particularly `Drop`, `Debug`, and `Clone`) - Forwarding impls that are only possible because the lifetime doesn't matter (like `impl Read for &mut R`) I omitted things that seemed like they could be more controversial, like the handful of iterators that have a `Item: 'static` despite the iterator having a lifetime or the `PartialEq` implementations [where the flipped one cannot elide the lifetime](https://internals.rust-lang.org/t/impl-type-parameter-aliases/9403/2?u=scottmcm). I also removed two lifetimes that turned out to be completely unused; see https://github.com/rust-lang/rust/issues/41960#issuecomment-464557423

Rollup merge of #58200 - RalfJung:str-as-mut-ptr, r=SimonSapin

2019-02-13T03:37:03+00:00

fix str mutating through a ptr derived from &self Found by Miri: In `get_unchecked_mut` (also used by the checked variants internally) uses `str::as_ptr` to create a mutable reference, but `as_ptr` takes `&self`. This means the mutable references we return here got created from a shared reference, which violates the shared-references-are-read-only discipline! For this by using a newly introduced `as_mut_ptr` instead.
