This is implemented with the freshly-released Wasmtime 19 and should
prevent beta breakage from wasm tests that was observed and fixed
in #122640 again.
`anstyle_svg` has some weird non-determinism in the width parameter, which makes tests blessed in one environment to fail in another. This is the *only* non-determinism detected so far, so we modify the diff check to ignore the first line of the SVG. In order for a test to fail/be updated by `--bless`, a different part of the file needs to also have changed.
For async closures, cap closure kind, get rid of `by_mut_body`
Right now we have three `AsyncFn*` traits, and three corresponding futures that are returned by the `call_*` functions for them. This is fine, but it is a bit excessive, since the future returned by `AsyncFn` and `AsyncFnMut` are identical. Really, the only distinction we need to make with these bodies is "by ref" and "by move".
This PR removes `AsyncFn::CallFuture` and renames `AsyncFnMut::CallMutFuture` to `AsyncFnMut::CallRefFuture`. This simplifies MIR building for async closures, since we don't need to build an extra "by mut" body, but just a "by move" body which is materially different.
We need to do a bit of delicate handling of the ClosureKind for async closures, since we need to "cap" it to `AsyncFnMut` in some cases when we only care about what body we're looking for.
This also fixes a bug where `<{async closure} as Fn>::call` was returning a body that takes the async-closure receiver *by move*.
This also helps align the `AsyncFn` traits to the `LendingFn` traits' eventual designs.
various clippy fixes
We need to keep the order of the given clippy lint rules before passing them.
Since clap doesn't offer any useful interface for this purpose out of the box,
we have to handle it manually.
Additionally, this PR makes `-D` rules work as expected. Previously, lint rules were limited to `-W`. By enabling `-D`, clippy began to complain numerous lines in the tree, all of which have been resolved in this PR as well.
Fixes#121481
cc `@matthiaskrgr`
This change is primarily meant to allow rustfmt to ignore all
diagnostics when using the `SilentEmitter`. Back in PR 121301 the
`SilentEmitter` was shared between rustc and rustfmt. This changed
rustfmt's behavior from ignoring all diagnostic to emitting fatal
diagnostics.
These changes allow rustfmt to maintain it's previous behaviour when
using the SilentEmitter, while allowing rustc code to still emit fatal
diagnostics.
Fix incorrect mutable suggestion information for binding in ref pattern.
For ref pattern in func param, the mutability suggestion has to apply to the binding.
For example: `fn foo(&x: &i32)` -> `fn foo(&(mut x): &i32)`
fixes#122415
compiletest: Add support for `//@ aux-bin: foo.rs`
Which enables ui tests to use auxiliary binaries. See the added
self-test for an example.
This is an enabler for the test in https://github.com/rust-lang/rust/pull/121573.
Use hir::Node helper methods instead of repeating the same impl multiple times
I wanted to do something entirely different and stumbled upon a bunch of cleanups
For ref pattern in func param, the mutability suggestion has to apply to the binding.
For example: `fn foo(&x: &i32)` -> `fn foo(&(mut x): &i32)`
fixes#122415
Fix heading anchors in doc pages.
This fixes the heading anchors on the standalone doc pages (the index, releases, etc.) so that the § symbol is only shown when the user hovers over the heading. This was changed in https://github.com/rust-lang/rust/pull/117662, but this CSS was not updated.
Provide structured suggestion for `#![feature(foo)]`

LL | struct S<'a, const N: S2>(&'a ());

= note: the only supported types are integers, `bool` and `char`
help: add `#![feature(adt_const_params)]` to the crate attributes to enable more complex and user defined types
