use std::sync::Mutex;

enum Foo { X(Mutex<Option<Foo>>) }
//~^ ERROR recursive type `Foo` has infinite size

impl Foo { fn bar(self) {} }

fn main() {}
Fix several issues with the struct and enum representability-checking logic. 2014-10-06 01:20:25 -05:00			`use std::sync::Mutex;`

			`enum Foo { X(Mutex<Option<Foo>>) }`
Detect cycles and specialize error reporting for Sized. It is important to get the `Sized` error usable, since that hits new users frequently. Further work is needed for the error reporting for non-Sized cycle cases; those currently just fallback to the old path. Also adjust tests. 2016-01-08 20:41:37 -06:00			//~^ ERROR recursive type `Foo` has infinite size
