A byproduct of using `<details>` and `<summary>` to show/hide detailed documentation was that clicking any part of a method heading (or impl heading) would show or hide the documentation. This was not super noticeable because clicking a link inside the method heading would navigate to that link. But clicking any unlinked black text in a method heading would trigger the behavior. That behavior was somewhat unexpected, and means that if you try to click a type name in a method heading, but miss by a few pixels, you get a confusing surprise. This change inhibits that behavior by putting an event listener on most summaries that cancels the event unless the event target was the summary itself. In practice, that means it cancels the event unless the target was the "[+]" / "[-]", because the rest of the heading is wrapped inside a `<div>`, which is the target for anything that doesn't have a more specific target.
Doc Jones mentioned that one of the things making it hard to get started is that the amount of information is overwhelming, between the dev-guide, contributing guide, and discussion platforms. This gives people a single link they can click to ask for help.
According to documentation, the listed errnos should only occur if the `copy_file_range` call cannot be made at all, so the assert be correct. However, since in practice file system drivers (incl. FUSE etc.) can return any errno they want, we should not panic here. Fixes rust-lang#91152
…llocator-api-in-tuple, r=davidtwco Suggestion to wrap inner types using 'allocator_api' in tuple This PR provides a suggestion to wrap the inner types in tuple when being along with 'allocator_api'. Closes rust-lang#83250 ```rust fn main() { let _vec: Vec<u8, _> = vec![]; //~ ERROR use of unstable library feature 'allocator_api' } ``` ```diff error[E0658]: use of unstable library feature 'allocator_api' --> $DIR/suggest-vec-allocator-api.rs:2:23 | LL | let _vec: Vec<u8, _> = vec![]; - | ^ + | ----^ + | | + | help: consider wrapping the inner types in tuple: `(u8, _)` | = note: see issue rust-lang#32838 <rust-lang#32838> for more information = help: add `#![feature(allocator_api)]` to the crate attributes to enable ```
…, r=Manishearth,GuillaumeGomez Inhibit clicks on summary's children A byproduct of using `<details>` and `<summary>` to show/hide detailed documentation was that clicking any part of a method heading (or impl heading) would show or hide the documentation.

Split inline const to two feature gates and mark expression position inline const complete This PR splits inline const in pattern position into its own `#![feature(inline_const_pat)]` feature gate, and make the usage in expression position complete. I think I have resolved most outstanding issues related to `inline_const` with rust-lang#89561 and other PRs. The only thing left that I am aware of is rust-lang#90150 and the lack of lifetime checks when inline const is used in pattern position (FIXME in rust-lang#89561). Implementation-wise when used in pattern position it has to be lowered during MIR building while in expression position it's evaluated only when monomorphizing (just like normal consts), so it makes some sense to separate it into two feature gates so one can progress without being blocked by another. ``@rustbot`` label: T-compiler F-inline_const
