Remove std::either 2013-12-25 21:55:05 -08:00			`enum Either<T, U> { Left(T), Right(U) }`
Update compile fail tests to use usize. 2015-01-08 22:02:42 +11:00			`struct S(Either<usize, usize>);`
rustc: Handle struct patterns where the expected type is an enum Previously, rustc would ICE if you matched on an enum-typed thing with a structure pattern. Error out correctly. 2013-05-02 15:38:19 -07:00
			`fn main() {`
Switch to purely namespaced enums This breaks code that referred to variant names in the same namespace as their enum. Reexport the variants in the old location or alter code to refer to the new locations: ``` pub enum Foo { A, B } fn main() { let a = A; } ``` => ``` pub use self::Foo::{A, B}; pub enum Foo { A, B } fn main() { let a = A; } ``` or ``` pub enum Foo { A, B } fn main() { let a = Foo::A; } ``` [breaking-change] 2014-11-06 00:05:53 -08:00			`match S(Either::Left(5)) {`
Fix testsuite errors 2015-01-12 01:01:44 -05:00			`Either::Right(_) => {}`

Modify primary span label for E0308 The previous output was unintuitive to users. 2023-01-02 18:00:33 -08:00			//~\| expected `S`, found `Either<_, _>`
Specific labels when referring to "expected" and "found" types 2019-11-13 14:16:56 -08:00			//~\| expected struct `S`
			//~\| found enum `Either<_, _>`
