Indentation failure with many generic arguments

[mkeeter]

When a set of generic arguments hits max-width, rustfmt seems to have trouble with indentation.

Here's an example:

fn omg() {
fn bar() {
self.core
.exchange::<LeaseBufReader<_, BUFSIZ>, _, LeaseBufWriter<_, BUFSIZ>, _>(
device_index,
src,
dest,
)
.map_err(RequestError::from)
}
}

$ rustfmt --config max_width=80 test.rs

fn omg() {
    fn bar() {
        self.core
.exchange::<LeaseBufReader<_, BUFSIZ>, _, LeaseBufWriter<_, BUFSIZ>, _>(
device_index,
src,
dest,
)
.map_err(RequestError::from)
    }
}

It properly indents the functions, but then gives up on the call to .exchange<...>.

Thanks for reaching out! I believe this is a duplicate of #5249. I'll hold off on closing this until I can confirm if PR #5252 also resolves this issue.

@mkeeter thanks again for opening up the issue. Confirming PR #5252 resolves this issue.

If you're curious what the new formatting is you can check out the test case I've added in the linked PR (tests/target/issue_5657.rs). When we merge the PR we'll close this as well.

Awesome, thanks!
