2019-10-13Implement Error::source on IntoStringErrorLinus Färnstrand-1/+1
IntoStringError only implemented Error::cause, which is deprecated. This implemements Error::source instead. Error::cause will still work as before, thanks to the default implementation.

2019-08-22Change variables names to be more consistent.Tomasz Różański-16/+16
Changed all instances of `c_str` into `cstr` in the documentation examples. This is also consistent with the module source code.
2019-08-11Rollup merge of #61969 - MikailBag:master, r=CentrilMark Rousskov-0/+6
Add #[repr(transparent)] for several types In some functions, types mentioned in this PR are transmuted into their inner value. Example for `PathBuf`: https://github.com/rust-lang/rust/blob/master/src/libstd/path.rs#L1132. This PR adds `#[repr(transparent)]` to those types, so their correct behavior doesn't depend on compiler details. (As far as I understand, currently that line, converting `PathBuf` to `Vec<u8>`, is UB).

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.
