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.
