// Destructuring struct variants would ICE where regular structs wouldn't

enum Foo {
    VBar { num: isize }

struct SBar { num: isize }

pub fn main() {
    let vbar = Foo::VBar { num: 1 };
    let Foo::VBar { num } = vbar;

Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 12:18:55 +00:00			`//@ run-pass`
librustc: Pass the node id so we don't fail on destructing struct variants. Fixes #11577. 2014-03-01 04:35:10 +00:00			`// Destructuring struct variants would ICE where regular structs wouldn't`

Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-26 00:06:52 +00:00			`VBar { num: isize }`

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 08:05:53 +00:00			`let vbar = Foo::VBar { num: 1 };`
			`let Foo::VBar { num } = vbar;`
