e7ecdc1664 Remove async fn from extern block tests 2020-11-28 21:59:30 -06:00
Ayaz Hafiz
3bf67c175d Don't drop blocks on foreign functions 
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

5ffccbb627 Properly format function signature in extern blocks 
Closes #4288

And we get to drop a method, which I think is a win :)

ce13ff15c3 Correctly create artificial span for formatting closure body 
This commit partially reverts #3934, opting to create a span that covers
the entire body of a closure when formatting a closure body with a
block-formatting strategy, rather than having the block-formatting code
determine if the visitor pointer should be rewound. The problem with
rewinding the visitor pointer is it may be incorrect for other (i.e.
non-artificial) AST nodes, as in the case of #4382.

Closes #4382

46ab14437e Don't flatten a block containing a single macro call 
We no longer flatten a block that looks like this:

```rust
match val {
    pat => { macro_call!() }
}
```

Currently, rust ignores trailing semicolons in macro expansion in
expression position (see https://github.com/rust-lang/rust/issues/33953)

If this is changed, flattening a block with a macro call may break the
user's code - the trailing semicolon will no longer parse if the macro
call occurs immediately on the right-hand side of the match arm
(e.g. `pat => macro_call!()`)

278e8da33b Add some basic tests for try{} expressions 
They failed to parse in rustfmt on me in https://github.com/rust-lang/rust/pull/77877, which looks like it's since been fixed, but I figured I'd send in some tests anyway.
