README.md

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
- On use of the default keyword
- On overlapping impls
Overlap checking with specialization enabled
- Basic overlap scenarios
  - Includes purely structural overlap
  - Includes purely trait-based overlap
  - Includes mix
- Overlap with differing polarity
Attempt to specialize without using default
Attempt to change impl polarity in a specialization
Attempt to rely on projection of a default type
- Rely on it externally in both generic and monomorphic contexts
- Rely on it both within an impl and outside it
