Matthew Jasper	ed32482534	Handle multiple trait-def projection candidates	2020-10-06 11:19:32 +01:00
Matthew Jasper	0dfa6ff3be	Avoid cycles from projection bounds ... Only check the own predicates of associated types when confirming projection candidates. Also consider implied bounds when comparing trait and impl methods.	2020-10-06 11:19:32 +01:00
Matthew Jasper	596d6c4b3b	Avoid cycle with projections from object types ... Normalizing `<dyn Iterator<Item = ()> as Iterator>::Item` no longer requires selecting `dyn Iterator<Item = ()>: Iterator`. This was previously worked around by using a special type-folder to normalize things.	2020-10-06 11:19:31 +01:00
Matthew Jasper	34e5a4992c	Normalize projection bounds when considering candidates ... This unfortunately requires some winnowing hacks to avoid now ambiguous candidates.	2020-10-06 11:19:31 +01:00
