Trait wgpu_core::hub::Access [−][src]
pub trait Access<A> { }Expand description
Type system for enforcing the lock order on shared HUB structures.
If type A implements Access<A>, that means we are allowed to proceed
with locking resource B after we lock A.
The implenentations basically describe the edges in a directed graph of lock transitions. As long as it doesn’t have loops, we can have multiple concurrent paths on this graph (from multiple threads) without deadlocks, i.e. there is always a path whose next resource is not locked by some other path, at any time.
