调研方向
首先比较 issue 中链接的 cust event 和 stream 文档，尤其是 Stream::wait_event，并确定哪些跨 stream 和跨 context 的情况实际受支持。在确定实现和测试范围之前，先定义缺失的行为及其阻塞因素；当支持状态或所需变更得到明确确立时，即视为完成。
由索引模型根据 Issue 内容生成。
描述
The following doc snippets seem to indicate that this is not yet supported:
Events can also be used to sequence tasks on multiple streams within the same context by specifying dependent tasks (not supported yet by cust).
~ https://docs.rs/cust/latest/cust/event/index.html
and
Sequencing between multiple streams can be achieved using events, which are not currently supported by cust.
~ https://docs.rs/cust/latest/cust/stream/index.html
However, the following bit makes it seem as though it is indeed supported, even across different devices/contexts.
Make the stream wait on an event.
All future work submitted to the stream will wait for the event to complete. Synchronization is performed on the device, if possible. The event may originate from different context or device than the stream.
~ https://docs.rs/cust/latest/cust/stream/struct.Stream.html#method.wait_event
Just wondering what the state of cross-stream/cross-context Event-based synchronization is. I'm happy to just go ahead and test, but I figured I would ask. This seems to be something supported on the Cuda level, not necessarily something which would need to be implemented in cust, but I could be wrong.
Also, if this needs to be implemented, I'm wondering if folks might have some thoughts on current blockers and such?
