OpenGuard

creusot_std::ghost::invariant

Struct OpenGuard 

Source 
pub struct OpenGuard<T: Protocol>(pub T::Public);
Expand description

Guard for NonAtomicInvariant::open.

This contains the public value, that must be unchanged for the borrow. Additionally, the guard asserts that the borrow satisfies its protocol.
