…bligation_cause_code` Most futures don't go through this code path, because they're caught by `maybe_note_obligation_cause_for_async_await`. But all generators do, and `maybe_note` is imperfect and doesn't catch all futures. Improve the error message for those it misses. At some point, we may want to consider unifying this with the code for `maybe_note_async_await`, so that `async_await` notes all parent constraints, and `note_obligation` can point to yield points. But both functions are quite complicated, and it's not clear to me how to combine them; this seems like a good incremental improvement.
It got merged so fast I didn't have time to make changes xD

Awesome, thanks! |

I'm pretty sure this can be used in multiple places! I recall seeing similar needs elsewhere.

Hmm, this is the only other place I see looking at opaque Future types:
pub fn get_impl_future_output_ty(&self, ty: Ty<'tcx>) -> Option<Binder<'tcx, Ty<'tcx>>> { |
that needs the
Output
type from the future - maybe I shouldn't have added this method and I should just use get_impl_future_output_ty().is_some()
instead?

Yes, that'd be a good idea. Could you make a small PR for it at some point?
