The check previously matched this, and suggested adding a missing
`struct`:
pub Foo(...):
It was probably intended to match this instead (semicolon instead of
colon):
pub Foo(...);
wildcard_enum_match_arm lint takes the enum origin into account

changelog: Enhancement: [`wildcard_enum_match_arm`]: Now lints missing private variants, for local enums
[#10250](https://github.com/rust-lang/rust-clippy/pull/10250)
<!-- changelog_checked -->
This now uses `node_to_string` for both missing and seen Ids, which includes
the snippet of code for which the Id was allocated.
Also removes the duplicated printing of `HirId`, as `node_to_string` includes that already.
Similarly, changes all other users of `node_to_string` that do so, and changes the output of `node_to_string`, which is now "$hirid ($what `$span` in $path)".
Expand docs section on Visual Studio to mention all three available extensions
A recent PR (#14012) by `@parthopdas` added mention of rust-analyzer.vs, his extension for Visual Studio 2022. I am submitting this PR to request that our extension (SourceGear Rust) be mentioned in that section as well, and also, for completeness, the VS_RustAnalyzer extension, by `@cchharris.`
Our extension is closed source, so I have clearly disclosed that. For consistency, I included brief mention of the licenses for the other two options as well. Also for the sake of consistency, I added marketplace and GitHub links for all 3.
The previously added paragraph by `@parthopdas` about his extension has been left intact.
minor: Bump `zip` to avoid `time-macros`
This fixes the compile time regression in #13876 and sneaks in two typo fixes spotted by `@cuishuang` (sorry for not preserving the commit attribution, but it's a little hard to manage it across repositories).
Sometimes it is necessary for handling vector to scalar pair transmutes,
but if the types are the same there is no need for this.
This improves runtime performance on simple-raytracer by 12%.
Strengthen validation of FFI attributes
Previously, `codegen_attrs` validated the attributes `#[ffi_pure]`, `#[ffi_const]`, and `#[ffi_returns_twice]` to make sure that they were only used on foreign functions. However, this validation was insufficient in two ways:
1. `codegen_attrs` only sees items for which code must be generated, so it was unable to raise errors when the attribute was incorrectly applied to macros and the like.
2. the validation code only checked that the item with the attr was foreign, but not that it was a foreign function, allowing these attributes to be applied to foreign statics as well.
This PR moves the validation to `check_attr`, which sees all items. It additionally changes the validation to ensure that the attribute's target is `Target::ForeignFunction`, only allowing the attributes on foreign functions and not foreign statics. Because these attributes are unstable, there is no risk for backwards compatibility. The changes also ending up making the code much easier to read.
This PR is best reviewed commit by commit. Additionally, I was considering moving the tests to the `attribute` subdirectory, to get them out of the general UI directory. I could do that as part of this PR or a follow-up, as the reviewer prefers.

Do not depend on Generator trait when deducing closure signature
1. Do not depend on `Generator` trait when deducing closure signature.
2. Compare the name of the `Generator::Return` associated item, rather than its order in the trait. Seems more stable this way.
Small bootstrap improvements
- i/o-less check for `xz` availability
- cache result of NixOS detection
- load correct `bootstrap` module even when a package of that name is installed
- no `-W semicolon_in_expressions_from_macros` – it is warn-by-default
- one type per variable (making dynamic typing less confusing)
- integrate python-side `--help` flag into the argument parser (makes `-hv` work as a short form of `--help --verbose`)
I even checked that it works with Python 2.
improve panic message for slice windows and chunks
before:
```text
thread 'main' panicked at 'size is zero', /rustc/1e225413a21fa69570bd3fefea9eb05e33f8b917/library/core/src/slice/mod.rs:809:44
```
```text
thread 'main' panicked at 'assertion failed: `(left != right)`
left: `0`,
right: `0`: chunks cannot have a size of zero', /rustc/1e225413a21fa69570bd3fefea9eb05e33f8b917/library/core/src/slice/mod.rs:843:9
```
after:
```text
thread 'main' panicked at 'chunk size must be non-zero', src/main.rs:4:22
```

Fixing confusion between mod and remainder
Like many programming languages, rust too confuses remainder and modulus. The `%` operator and the associated `Rem` trait is (as the trait name suggests) the remainder, but since most people are linguistically more familiar with the modulus the documentation sometimes claims otherwise. This PR tries to fix this problem in rustc.
