Compact where clause style

[djc]

rustfmt currently reformats my code like this, which doesn't seem like an improvement to me:

-pub trait FetchBuilderMessages where Self: Sized {
+pub trait FetchBuilderMessages
+where
+    Self: Sized,
+{

I find the 3 extra lines a bad trade-off in this case for the length of the where clause. However, looking at the configurations relating to where clauses, keeping them on the same line for clauses below some length limit does not seem to be an option.

where_single_line gives you a more compact layout. We're unlikely to ever single-line a trait decl and where clause (though I think we do it if the body is empty too).

[djc]

The README states you're mostly willing to add config options to accomodate different styles. Can you explain why this case is different?

[nrc]

Ah, sorry, the README is somewhat out of date in this respect (I didn't even remember that was there). That certainly was the case, but now that we have mostly settled on an 'official' style and we are approaching a 1.0 release, we are trying to consolidate the options and reduce the overall number.

This is a blocker for me, preventing me from using rustfmt. I'm not sure if the official opinion on this has changed sometime in the past 5 years, but there is still no option for this so I'm just going to assume rustfmt intentionally does not support my code style.
