```rust
use core::future::Future;
trait DesugaredAsyncTrait {
fn foo(&self) -> impl Future<Output = ()> + Send;
}
impl DesugaredAsyncTrait for () {
$0
}
```
**Before this PR**
```rust
use core::future::Future;
trait DesugaredAsyncTrait {
fn foo(&self) -> impl Future<Output = ()> + Send;
}
impl DesugaredAsyncTrait for () {
async fn foo(&self) -> () {
$0
}
}
```
**After this PR**
```rust
use core::future::Future;
trait DesugaredAsyncTrait {
fn foo(&self) -> impl Future<Output = ()> + Send;
}
impl DesugaredAsyncTrait for () {
async fn foo(&self) {
$0
}
}
