Struct concordium_std::StateRef

source · [−]

pub struct StateRef<'a, V> { /* private fields */ }

Expand description

The StateRef behaves akin the type &'a V, except that it is not copyable. It should be used as MutexGuard or similar types which guard access to a resource.

The type implements Deref to V, and that is the intended, and only, way to use it.
