This caused a diagnostic regression, originally it was: ``` warning: unresolved link to `std::process::Comman` --> link.rs:3:10 | 3 | //! [a]: std::process::Comman | ^^^^^^^^^^^^^^^^^^^^ no item named `Comman` in module `process` | = note: `#[warn(broken_intra_doc_links)]` on by default ``` but after that PR rustdoc now displays ``` warning: unresolved link to `std::process::Comman` --> link.rs:1:14 | 1 | //! Links to [a] [link][a] | ^^^ no item named `Comman` in module `process` | = note: `#[warn(broken_intra_doc_links)]` on by default ``` which IMO is much less clear.
NatVis files describe how to display types in some Windows debuggers,
such as Visual Studio, WinDbg, and VS Code.
This commit makes several improvements:
* Adds visualizers for Rc<T>, Weak<T>, and Arc<T>.
* Changes [size] to [len], for consistency with the Rust API.
Visualizers often use [size] to mirror the size() method on C++ STL
collections.
* Several visualizers used the PVOID and ULONG typedefs. These are part
of the Windows API; they are not guaranteed to always be defined in a
pure Rust DLL/EXE. I converted PVOID to `void*` and `ULONG` to
`unsigned long`.
* Cosmetic change: Removed {} braces around the visualized display
for `Option` types. They now display simply as `Some(value)` or
`None`, which reflects what is written in source code.
* The visualizer for `alloc::string::String` makes assumptions about
the layout of `String` (it casts `String*` to another type), rather
than using symbolic expressions. This commit changes the visualizer
so that it simply uses symbolic expressions to access the string
data and string length.
- Replace {} with the stringified expr
Giant thank you to `@danielhenrymantilla` for figuring out how to make
this work ❤️
- Note that this is just an approximation and it would be better to add
a doc-comment

Fix ICE when pointing at multi bytes character Fixes rust-lang#80134 Seems this ICE was introduced by rust-lang#73953, checking width of span to avoid ICE.
…u-se slightly more typed interface to panic implementation The panic payload is currently being passed around as a `usize`. However, it actually is a pointer, and the involved types are available on all ends of this API, so I propose we use the proper pointer type to avoid some casts. Avoiding int-to-ptr casts also makes this code work with `miri -Zmiri-track-raw-pointers`.
Improvements to NatVis support

so that it simply uses symbolic expressions to access the string
data and string length.
* The visualizers for `str` and `String` now place the character data
array under a synthetic `[chars]` node. When expanding a `String`
node, users rarely want to see an array of characters. This just places
them behind one expansion node / level.
Use `desc` as a doc-comment for queries if there are no doc comments This at least gives *some* idea of what the query does even if it's not very readable. Some examples:    I want to turn `{}` into either `_` or the stringified expr, but [I'm not sure how to do that](https://rust-lang.zulipchat.com/#narrow/stream/122651-general/topic/Evaluate.20format.20string.20in.20proc-macro). In the meantime, this is better than having no docs at all.
…llaumeGomez Revert "Cleanup markdown span handling" Reverts rust-lang#80244. This caused a diagnostic regression, originally it was: ``` warning: unresolved link to `std::process::Comman` --> link.rs:3:10 | 3 | //!

remove empty wraps, don't return Results from from infallible functions This makes code easier to understand because it is more obvious when a function actually can't fail (return Err or None) Make functions that only ever return Some(x), return x directly Remove return type from functions that return Option<(), Err> but would only ever return Ok(()). Found with `clippy::unnecessary_wraps`
where possible, pass slices instead of &Vec or &String (clippy::ptr_arg)
