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)]`
Fix bug in test for E0199 and add test for E0198. In particular, as far as I can tell from the error diagnostics, the former test for E0199 was actually a test for E0198, and there was no test for E0198. (I am assuming that one of my previous changes to the `unsafe impl` checking fixed a latent bug in how these two cases were differentiated.) 2016-10-12 16:53:57 +02:00
			`struct Foo;`

syntax: Rewrite parsing of impls Properly parse impls for the never type `!` Recover from missing `for` in `impl Trait for Type` Prohibit inherent default impls and default impls of auto traits Change wording in more diagnostics to use "auto traits" Some minor code cleanups in the parser 2017-12-02 22:15:03 +03:00			`unsafe impl !Send for Foo { } //~ ERROR E0198`
