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)]`
Introduce marker types for indicating variance and for opting out of builtin bounds. Fixes #10834. Fixes #11385. cc #5922. 2014-01-22 14:03:02 -05:00
Don't use NoSend/NoSync in tests 2015-01-11 13:14:39 +01:00			`use std::marker::Sync;`

			`struct Foo { a: isize }`
			`impl !Sync for Foo {}`

Rename `Share` to `Sync` This leaves the `Share` trait at `std::kinds` via a `#[deprecated]` `pub use` statement, but the `NoShare` struct is no longer part of `std::kinds::marker` due to #12660 (the build cannot bootstrap otherwise). All code referencing the `Share` trait should now reference the `Sync` trait, and all code referencing the `NoShare` type should now reference the `NoSync` type. The functionality and meaning of this trait have not changed, only the naming. Closes #16281 [breaking-change] 2014-08-05 16:40:04 -07:00			`fn bar<T: Sync>(_: T) {}`

Added tests to make tidy 2014-02-05 16:33:10 -06:00			`bar(x);`
Reword E0044 and message for `!Send` types - Reword E0044 help. - Change error message for types that don't implement `Send` 2018-02-10 21:01:49 -08:00			//~^ ERROR `Foo` cannot be shared between threads safely [E0277]
