introduce `negative_impls` feature gate and document They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits. 2020-01-09 05:56:38 -05:00			`#![feature(negative_impls)]`
Adjust tests for feature gate, and add tests for the gate itself 2015-12-30 15:25:31 -08:00			`#![feature(specialization)]`
Add basic specialization tests, including for default item inheritance. Updates some of the coherence tests as well. 2015-12-28 15:40:11 -08:00
