In order to switch `clippy::uninlined_format_args` from pedantic to
style, all existing tests must not raise a warning. I did not want to
change the actual tests, so this is a relatively minor change that:
* add `#![allow(clippy::uninlined_format_args)]` where needed
* normalizes all allow/deny/warn attributes
* all allow attributes are grouped together
* sorted alphabetically
* the `clippy::*` attributes are listed separate from the other ones.
* deny and warn attributes are listed before the allowed ones
changelog: none
If I understand it correctly, we were first creating a type with a
`RegionKind::ReErased` region and then deleted it again in
`util::implements_trait` with:
cx.tcx.erase_regions(&ty);
causing the type query to fail.
It looks like using `ReEmpty` works around that deletion.
This `match` is not moving the `String`:
```rust
fn foo(x: Option<String>) -> i32 {
match x {
Some(_) => 1,
None => 2,
}
}
```
With this change, it will be linted and suggested to add `*` to deref it.
```rust
fn foo(x: &Option<String>) -> i32 {
match *x {
Some(_) => 1,
None => 2,
}
}
```
