Enum Access 

pub enum Access {
    Read,
    Write,
    ReadWrite,
}

Access kind for a single block use. Drives the cross-stream dependency edges the resource queues during DeviceMemoryResource::prepare_block_use and the events it records during DeviceMemoryResource::finish_block_use.

• Access::Read — the work consumes the block’s bytes. Must wait on any prior write on a different stream. The resulting event advances that stream’s read frontier so future writers (and the eventual deallocate) can wait on it.
• Access::Write — the work overwrites the block’s bytes unconditionally. Must wait on the block’s prior write AND all outstanding reads on different streams. The resulting event advances that stream’s write frontier. Other streams’ concurrent uses remain visible until their completion is independently ordered.
• Access::ReadWrite — both. Same wait set as Write, and the resulting event likewise advances its write frontier.
