- Remove some redundant `.clone_for_update()` and `.indent(IndentLevel::single())`
Example
---
```rust
fn main() {
if true {
$0if true
&& false
{
foo()
}
}
}
```
**Before this PR**
```rust
fn main() {
if true {
match true
&& false {
true => foo(),
_ => (),
}
}
}
```
**After this PR**
```rust
fn main() {
if true {
match true
&& false {
true => foo(),
_ => (),
}
}
}
```
the `check_ptr_ptr_cast` function had an early return when the source and
destination dyn trait objects shared the same principal trait def id:
if src_principal == dst_principal {
return Ok(());
}
this bypassed all three remaining checks that the code comment explicitly
listed as required: generic argument equality, projection equality, and
the auto-trait superset check. as a result, casts like
`*mut dyn Trait as *mut (dyn Trait + Send)` were silently accepted
instead of emitting E0804.
the fix removes the early return. `CastError::PtrPtrAddingAutoTraits` and
its diagnostic were already implemented — they just couldn't be reached.
the supertrait case (`trait Trait: Send`) continues to work correctly
because the auto-trait check already accounts for implied auto traits via
supertrait elaboration.
Currently the rustfmt slow test fails if you don't have a nightly toolchain installed. We install a nightly toolchain on CI, but it's a little confusing that tests can fail on a fresh checkout on a new laptop. Instead, skip this test if there's no nightly toolchain.
internal: Skip rustfmt test if nightly toolchain is missing
Example
---
```rust
enum Enum { TupleV(u32), RecordV { field: u32 }, UnitV }
use Enum::*;
fn func() {
if let $0 = unknown {}
}
```
**Before this PR**
```text
...
ev RecordV
ev TupleV
ev UnitV
bn RecordV {…} RecordV { field$1 }$0
bn TupleV(…) TupleV($1)$0
bn UnitV UnitV$0
kw mut
kw ref
```
**After this PR**
```text
...
bn RecordV {…} RecordV { field$1 }$0
bn TupleV(…) TupleV($1)$0
bn UnitV UnitV$0
kw mut
kw ref
```
