2019-02-20Rollup merge of #58553 - scottmcm:more-ihle, r=Centrilkennytm-2/+2
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<R: Read + ?Sized> 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

2018-11-12Auto merge of #55278 - Centril:constification-1, r=alexcrichtonbors-1/+1
Minor standard library constification This PR makes some bits of the standard library into `const fn`s. I've tried to be as aggressive as I possibly could in the constification.

2017-11-09std: Avoid use of `libc` in portable modulesAlex Crichton-3/+3
This commit removes usage of the `libc` crate in "portable" modules like those at the top level and `sys_common`. Instead common types like `*mut u8` or `u32` are used instead of `*mut c_void` or `c_int` as well as switching to platform-specific functions like `sys::strlen` instead of `libc::strlen`.
