On bootstrap the IntoIterator trait is not implemented yet for arrays.
Searching for "reduce" currently puts the `reduce` alias for `fold` above the actual `reduce` function. The `reduce` function already has a cross-reference for `fold`, and vice versa.
Each label needs to be separated by a comma (see the ICE issue template for an example of correct usage). As a result of this problem, the `regression-untriaged` label has not been automatically added to issues opened with this template. See c127530 for another example of this.
…rent process This is a straightforward wrapper that uses the existing helpers for C string handling and errno handling. Having this available is convenient for UNIX utility programs written in Rust, and avoids having to call the unsafe `libc::chroot` directly and handle errors manually, in a program that may otherwise be entirely safe code.
Use flex more consistently Builds on rust-lang#84376, related to rust-lang#84354. - Fully replaces `float: right` with `flex` on `.content .out-of-band`. - Uses `flex` more consistently with existing usage (on `h3`, `h4`, etc.). Tested on various widths to make sure the pages behave as before.
Vastly improves coverage spans for macros Fixes: rust-lang#84561 This resolves problems where macros like `trace!(...)` would show zero coverage if tracing was disabled, and `assert_eq!(...)` would show zero coverage if the assertion did not fail, because only one coverage span was generated, for the branch. This PR started with an idea that I could just drop branching blocks with same span as expanded macro. (See the fixed issue for more details.) That did help, but it didn't resolve everything. I also needed to add a span specifically for the macro name (plus `!`) to ensure the macro gets coverage even if it's internal expansion adds conditional branching blocks that are retained, and would otherwise drop the outer span. Now that outer span is _only_ the `(argument, list)`, which can safely be dropped now), because the macro name has its own span. While testing, I also noticed the spanview debug output can cause an ICE on a function with no body. The workaround for this is included in this PR (separate commit). r? ````@tmandry```` cc? ````@wesleywiser````
Point out that behavior might be switched on 2015 and 2018 too one day Reword documentation to make it clear that behaviour can be switched on older editions too, one day in the future. It doesn't *have* to be switched, but I think it's good to have it as an option and re-evaluate it a few months/years down the line when e.g. the crates that showed up in crater were broken by different changes in the language already. cc rust-lang#25725, rust-lang#65819, rust-lang#66145, rust-lang#84147 , and rust-lang#84133 (comment)
…r=nikomatsakis Don't rebind in `transitive_bounds_that_define_assoc_type` Fixes rust-lang#83737 Fixes rust-lang#84604 Also fixes another issue that I don't have a test for, popped up in [zulip](https://rust-lang.zulipchat.com/#narrow/stream/144729-wg-traits/topic/Duplicate.20symbol.20error.20.2384604/near/236570445) r? ``@nikomatsakis``
…vink Minor grammar tweaks for readability to btree internals I was reading through the btree implementation and I noticed some grammar that could be improved in Node.rs so here is what I think would be a minor improvement.
…ss-for-search-results, r=Nemo157 Remove unnecessary CSS rules for search results Discovered that this was useless when working on rust-lang/docs.rs#1382. r? `````@Nemo157`````
…in-search-results, r=Nemo157 Remove unneeded bottom margin on search results As you can see, there is still more than enough space at the bottom:  r? ```@Nemo157```
…lett make feature recommendations optional this is what we're already doing for other feature gates, so it's better to be consistent
Drop alias `reduce` for `fold` - we have a `reduce` function Searching for "reduce" currently puts the `reduce` alias for `fold` above the actual `reduce` function. The `reduce` function already has a cross-reference for `fold`, and vice versa.
…te, r=Mark-Simulacrum Fix labels for regression issue template Each label needs to be separated by a comma (see the ICE issue template for an example of correct usage).

Add std::os::unix::fs::chroot to change the root directory of the current process This is a straightforward wrapper that uses the existing helpers for C string handling and errno handling. Having this available is convenient for UNIX utility programs written in Rust, and avoids having to call the unsafe `libc::chroot` directly and handle errors manually, in a program that may otherwise be entirely safe code.
