Do not show docs link when lint doesn't start with "clippy::"
This small change ensures that if the diagnostic functions are called from outside of Clippy, a docs link is not displayed.

Add a `min_type_alias_impl_trait` feature gate
This new feature gate only permits type alias impl trait to be constrained by function and trait method return types. All other possible constraining sites like const/static types, closure return types and binding types are now forbidden and gated under the `type_alias_impl_trait` and `impl_trait_in_bindings` feature gates (which are both marked as incomplete, as they have various ways to ICE the compiler or cause query cycles where they shouldn't).
r? `@nikomatsakis`
This is best reviewed commit-by-commit
To be clear, by default running `x.py test` on a checkout of the beta branch
currently fails, and with this change will continue to fail, because `x.py
tests` runs `x.py test src/tools/tidy` which tries to run `rustfmt` and that
will fail because the `rustfmt` binary is pinned to the current nighlty and we
do not attempt to distribute one for the beta builds.
This change gives a better error message than the current message, which is just
"./x.py fmt is not supported on this channel" without providing any hint about
what one might do about that problem.
(update: placated tidy.)
Refactor unit types
Ref: #6724
r? `@flip1995`
Changes:
1. Extract `unit_types` from `types` group.
2. Move lints of `unit_types` to their own modules.
Notes:
Other lints of `unit_types` is still scattered around the `clippy_lints`, e.g. `result_unit_err` or `option_map_unit_fn`.
These should be addressed in another PR.
changelog: none
83054 introduced validation of scalar range attributes, but panicking
code that uses the attribute remained reachable. Use `delay_span_bug`
instead to avoid the ICE.
wrong_self_convention: fix lint in case of `to_*_mut` method
fixes#6758
changelog: wrong_self_convention: fix lint in case of `to_*_mut` method. When a method starts with `to_` and ends with `_mut`, clippy expects a `&mut self` parameter, otherwise `&self`.
Any feedback is welcome. I was also thinking if shouldn't we treat `to_` the same way as `as_`. Namely to accept `self` taken: `&self` or `&mut self`.
Consider functions to be reachable for code coverage purposes, either
when they reach the code generation directly, or indirectly as inlined
part of another function.
When codegenning code coverage use the instance that coverage data was
originally generated for, to ensure basic level of compatibility with
MIR inlining.
Move some utils to `clippy_utils::ty`
changelog: none
`clippy_utils::*` has become a giant junk drawer. This is one step to clean it up a bit. One motivation is that I believe the long import statements cause more merge conflicts.
We now lint on *any* use of `procedural-masquerade` crate. While this
crate still exists, its main reverse dependency (`cssparser`) no longer
depends on it. Any crates still depending off should stop doing so, as
it only exists to support very old Rust versions.
If a crate actually needs to support old versions of rustc via
`procedural-masquerade`, then they'll just need to accept the warning
until we remove it entirely (at the same time as the back-compat hack).
The latest version of `procedural-masquerade` does not work with the
latest rustc, but trying to check for the version seems like more
trouble than it's worth.
While working on this, I realized that the `proc-macro-hack` check was
never actually doing anything. The corresponding enum variant in
`proc-macro-hack` is named `Value` or `Nested` - it has never been
called `Input`. Due to a strange Crater issue, the Crater run that
tested adding this did *not* end up testing it - some of the crates that
would have failed did not actually have their tests checked, making it
seem as though the `proc-macro-hack` check was working.
The Crater issue is being discussed at
https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/Nearly.20identical.20Crater.20runs.20processed.20a.20crate.20differently/near/230406661
Despite the `proc-macro-hack` check not actually doing anything, we
haven't gotten any reports from users about their build being broken.
I went ahead and removed it entirely, since it's clear that no one is
being affected by the `proc-macro-hack` regression in practice.
