Struct SlabOrigin 

Source 
pub struct SlabOrigin<T, L: RawLock = RawMutex, const SLAB_SIZE: usize = DEFAULT_SLAB_ALLOCATOR_SLAB_SIZE, const TRACK_OBJECT_COUNT: bool = false> { /* private fields */ }
Expand description

A helper type to store the originating slab allocator for instanced allocations.

This type wraps Option<NonNull<SlabAllocator<...>>> and provides safe Send and Sync implementations, allowing the containing object to be shared across threads.
