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
defaulttype
