Fix `allow_internal_unstable` for `(min_)specialization` Fixes #119950 Blocked on #119949 (comment doesn't make sense until that merges) I'd like to follow this up and look for more instances of not properly checking spans for features but I wanted to fix the motivating issue.
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
