2018-03-03core: Stabilize FusedIteratorUlrik Sverdrup-7/+7
FusedIterator is a marker trait that promises that the implementing iterator continues to return `None` from `.next()` once it has returned `None` once (and/or `.next_back()`, if implemented). The effects of FusedIterator are already widely available through `.fuse()`, but with stable `FusedIterator`, stable Rust users can implement this trait for their iterators when appropriate.

2018-01-05Rollup merge of #47030 - ollie27:stab, r=alexcrichtonkennytm-2/+6
Correct a few stability attributes * The extra impls for `ManuallyDrop` were added in #44310 which was only stabilised in 1.22.0. * The impls for `SliceIndex` were stabilised in #43373 but as `RangeInclusive` and `RangeToInclusive` are still unstable the impls should remain unstable. * The `From` impls for atomic integers were added in #45610 but most atomic integers are still unstable. * The `shared_from_slice2` impls were added in #45990 but they won't be stable until 1.24.0. * The `Mutex` and `RwLock` impls were added in #46082 but won't be stable until 1.24.0.

2017-09-29Auto merge of #44174 - jimmycuadra:try-from-infallible, r=sfacklerbors-5/+2
Add blanket TryFrom impl when From is implemented. Adds `impl<T, U> TryFrom<T> for U where U: From<T>`. Removes `impl<'a, T> TryFrom<&'a str> for T where T: FromStr` (originally added in #40281) due to overlapping impls caused by the new blanket impl. This removal is to be discussed further on the tracking issue for TryFrom. Refs #33417. /cc @sfackler, @scottmcm (thank you for the help!), and @aturon

This verifies that TrustedRandomAccess has no side effects when the iterator item implements Copy. This also implements TrustedLen and TrustedRandomAccess for str::Bytes.

Remove str_eq lang item It's not really a lang item. Also remove outdated note. The reference uses this as an example so it has to be updated.

Replace str's transmute() calls with pointer casts After the following conversation in #rust-lang: ``` [14:43:50] <Ixrec> TIL the implementation of from_utf_unchecked is literally just "mem::transmute(x)" [14:43:59] <Ixrec> no wonder people keep saying transmute is overpowered [15:15:30] <eddyb> Ixrec: it should be a pointer cast lol [15:15:46] <eddyb> unless it doesn't let you [16:50:34] <Ixrec> https://play.rust-lang.org/?gist=d1e6b629ad9ec1baf64ce261c63845e6&version=stable seems like it does let me [16:52:35] <eddyb> Ixrec: yeah that's the preferred impl [16:52:46] <eddyb> Ixrec: it just wasn't in 1.0 [16:52:50] <eddyb> IIRC [16:53:00] <eddyb> (something something fat pointers) ``` Since I already wrote half of the preferred impls in the playground, might as well make an actual PR.

2017-07-20std: Cut down #[inline] annotations where not necessaryAlex Crichton-6/+6
This PR cuts down on a large number of `#[inline(always)]` and `#[inline]` annotations in libcore for various core functions. The `#[inline(always)]` annotation is almost never needed and is detrimental to debug build times as it forces LLVM to perform inlining when it otherwise wouldn't need to in debug builds. Additionally `#[inline]` is an unnecessary annoation on almost all generic functions because the function will already be monomorphized into other codegen units and otherwise rarely needs the extra "help" from us to tell LLVM to inline something. Overall this PR cut the compile time of a [microbenchmark][1] by 30% from 1s to 0.7s. [1]: https://gist.github.com/alexcrichton/a7d70319a45aa60cf36a6a7bf540dd3a

This commit * Refactors the collect_lib_features function to work in a non-checking mode (no bad pointer needed, and list of lang features). * Introduces checking whether unstable/stable tags for a given feature have inconsistent tracking issues. * Fixes such inconsistencies throughout the codebase.

Move any extra logic that the former had into the latter, so they're consistent.
