then we just suggest the first legal position where you could inject a use.
To do this, I added `inject_use_span` field to `ModSpans`, and populate it in
parser (it is the span of the first token found after inner attributes, if any).
Then I rewrote the use-suggestion code to utilize it, and threw out some stuff
that is now unnecessary with this in place. (I think the result is easier to
understand.)
Then I added a test of issue 87613.
TraitKind -> Trait
TyAliasKind -> TyAlias
ImplKind -> Impl
FnKind -> Fn
All `*Kind`s in AST are supposed to be enums.
Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order.
Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.
* Fixed Comment removed between type name and = issue
* Fixed where clause issue and pass the full span
* has_where condition inline
* Fixed indentation error on where clause
* Removed tmp file
A code like
```rust
extern "C" {
fn f() {
fn g() {}
}
}
```
is incorrect and does not compile. Today rustfmt formats this in a way
that is correct:
```rust
extern "C" {
fn f();
}
```
But this loses information, and doesn't have to be done because we know
the content of the block if it is present. During development I don't
think rustfmt should drop the block in this context.
Closes#4313
* Added test cases
* Fixed if condition comment issue
* Fixed extern C issue
* Removed previous test case
* Removed tmp file
* honor the authors intent
* Changed the file name to its original name
* Removed extra whitespace
Previously, non-trivial type aliases in extern blocks were dropped by
rustfmt because only the type alias name would be passed to a rewritter.
This commit fixes that by passing all type information (generics,
bounds, and assignments) to a type alias rewritter, and consolidates
`rewrite_type_alias` and `rewrite_associated_type` as one function.
