pub trait LockAfter<A> { }
Expand description

Marker trait that indicates that Self can be locked after A.

This should be implemented for lock types to specify that, in the lock ordering graph, A comes before Self. So if B: LockAfter<A>, lock type B can be acquired after A but A cannot be acquired after B.

Note, though, that it’s preferred to use the [impl_lock_after] macro instead of writing trait impls directly to avoid the possibility of lock ordering cycles.
