> I do hope rustc gets better at lifetime compilation errors cause some of them can be very very gnarly.

When this happens, file tickets! We do our best to improve diagnostics over time, but the best improvements have been reactive, by fixing a case that we never encountered but our users did.

will keep that in mind going forward! The most recent ones which I have been hitting are around "higher-ranked lifetime error"

I know my way around this now, which is to literally binary search over the timeline of my edits (commenting out code and then reintroducing it) to see what causes the compiler to trip over (there might be better ways to debug this, and I am all ears)

Most of the times this error is several layers deep in my application so even tho I want to ticket it up, not being able to create a minimal repo for anyone to iterate against feels like a bit of wasted energy on all sides, do let me know if I should change this way of thinking and I can promise myself to start being more proactive.

If it's public code, a link to a branch with the issue can still be useful. Looking at the compiler internals you can get a better sense on how to minimize the issue. That being said, not having a minimised repro lowers the chance of it getting addressed quickly.

Even if you have already figured out how to deal with it, your future colleagues might not, and by improving the diagnostic you would also be getting that time manually commenting code back.
