Niko Matsakis	bc9ae36dba	Separate supertrait collection from processing a TraitDef. This allows ... us to construct trait-references and do other things without forcing a full evaluation of the supertraits. One downside of this scheme is that we must invoke `ensure_super_predicates` before using any construct that might require knowing about the super-predicates.	2015-03-04 15:06:33 -05:00
Niko Matsakis	cf73e36ab0	Rework trait-bound-conversion so be based on the AST and rework collect ... to pass in the appropriate ast::generics etc	2015-02-24 16:27:23 -05:00
Niko Matsakis	0d9e473be9	Comprehence cycle detection in collect. In some cases, the cycles we ... report are not *necessary* cycles, but we'll work on refactoring them over time. This overlaps with the cycle detection that astconv already does: I left that code in because it gives a more targeted error message, though perhaps less helpful in that it doesn't give the full details of the cycle.	2015-02-24 16:27:22 -05:00
