It is not always obvious that people could see the docs for `&` especially for beginners, it also helps learnability.
This removes the incorrect error, but doesn't show the documentation anywhere.
…r around documenting re-exports
Now this actually tests the links are generated correctly
Related to rust-lang#65354 - Pass through the replacement text to `markdown.rs` - Add some tests - Add a state machine that actually replaces the text when parsing Markdown
- Preserve suffixes when displaying - Rename test file to match `intra-link*` - Remove unnecessary .clone()s - Improve comments and naming - Fix more bugs and add tests - Escape intra-doc link example in public documentation
Upgrade Chalk to 0.21 Two commits here. First commit actually does the upgrade. Second commit has some changes to make more tests in compare-mode=chalk pass. The `PlaceholdersCollector` and `RegionsSubstitutor` bits are bit a hacky, but only insomuch as `ParamsSubstitutor` is. These won't be needed eventually. r? @nikomatsakis
…crum BTreeMap: introduce marker::ValMut and reserve Mut for unique access The mutable BTreeMap iterators (apart from `DrainFilter`) are double-ended, meaning they have to rely on a front and a back handle that each represent a reference into the tree. Reserve a type category `marker::ValMut` for them, so that we guarantee that they cannot reach operations on handles with borrow type `marker::Mut`and that these operations can assume unique access to the tree. Including rust-lang#75195, benchmarks report no genuine change: ``` benchcmp old new --threshold 5 name old ns/iter new ns/iter diff ns/iter diff % speedup btree::map::iter_100 3,333 3,023 -310 -9.30% x 1.10 btree::map::range_unbounded_vs_iter 36,624 31,569 -5,055 -13.80% x 1.16 ``` r? @Mark-Simulacrum
…asper do not apply DerefMut on union field This implements the part of [RFC 2514](https://github.com/rust-lang/rfcs/blob/master/text/2514-union-initialization-and-drop.md) about `DerefMut`. Unlike described in the RFC, we only apply this warning specifically when doing `DerefMut` of a `ManuallyDrop` field; that is really the case we are worried about here. @matthewjasper suggested I patch `convert_place_derefs_to_mutable` and `convert_place_op_to_mutable` for this, but I could not find anything to do in `convert_place_op_to_mutable` and this is sufficient to make the test pass. However, maybe there are some other cases this misses? I have no familiarity with this code. This is a breaking change *in theory*, if someone used `ManuallyDrop<T>` in a union field and relied on automatic `DerefMut`. But on stable this means `T: Copy`, so the `ManuallyDrop` is rather pointless. Cc rust-lang#55149
Add a regression test for issue-72793 Adds a regression test for rust-lang#72793, which is fixed by rust-lang#75443. Note that this won't close the issue as the snippet still shows ICE with `-Zmir-opt-level=2`. But it makes sense to add a test anyway.
Enable some of profiler tests on Windows-gnu CC rust-lang#61266 Because of force-push GitHub didn't let me reopen rust-lang#75184 Because of the GCC miscompilation, generated binaries either segfault or `.profraw` is malformed. Clang works fine but we can't use it on the CI. However we can still test the IR for the proper instrumentation so let's do it.
…st-doc-alias, r=ollie27 Add check for doc alias on assoc const in trait impl Fixes rust-lang#73721. r? @ollie27
…ing_issues, r=steveklabnik Unstable Book: add links to tracking issues for FFI features
`impl Rc::new_cyclic` References rust-lang#75861 r? @Dylan-DPC
Link vec doc to & reference It is not always obvious that people could see the docs for `&` especially for beginners, it also helps learnability.
Remove disambiguators from intra doc link text Closes rust-lang#65354. r? @Manishearth The commits are mostly atomic, but there might be some mix between them here and there. I recommend reading 'refactor ItemLink' and 'refactor RenderedLink' on their own though, lots of churn without any logic changes.
…uillaumeGomez Fix intra-doc links on pub re-exports Partial fix for rust-lang#76073 - This removes the incorrect error, but doesn't show the documentation anywhere. r? @GuillaumeGomez
…odrAus Use Arc::clone and Rc::clone in documentation This PR replaces uses of `x.clone()` by `Rc::clone(&x)` (or `Arc::clone(&x)`) to better match the documentation for those types. @rustbot modify labels: T-doc
Add missing link in README
Move some Vec UI tests into alloc unit tests A bit of work towards rust-lang#76268, makes a number of the Vec UI tests that are simply running code into unit tests. Ensured that they are being run when testing liballoc locally.
