Trait predicates for types which have errors may still evaluate to OK leading to downstream ICEs. Now we return a selection error for such types in candidate assembly and thereby prevent such issues
This directory contains the test for incorrect usage of specialization that should lead to compile failure. Those tests break down into a few categories:
-
Feature gating
-
Overlap checking with specialization enabled
- Basic overlap scenarios
- Includes purely structural overlap
- Includes purely trait-based overlap
- Includes mix
- Overlap with differing polarity
- Basic overlap scenarios
-
Attempt to rely on projection of a
default
type
