// rust-lang/rust#47215: at one time, the compiler categorized // thread-local statics as a temporary rvalue, as a way to enforce // that they are only valid for a given lifetime. // // The problem with this is that you cannot move out of static items, // but you *can* move temporary rvalues. I.e., the categorization // above only solves half of the problem presented by thread-local // statics. #![feature(thread_local)] #[thread_local] static mut X: ::std::sync::atomic::AtomicUsize = ::std::sync::atomic::AtomicUsize::new(0); fn main() { unsafe { let mut x = X; //~ ERROR cannot move out of static item `X` [E0507] let _y = x.get_mut(); } }
