Is it ok to use `ArcSwap` in async environment?

[byte-sourcerer]

For example, would it causes deadlock in the async environment?

ArcSwap is lock-free. There is no way to cause a deadlock with it.

However, if you hold too many Guards to the same arc-swap, you may get a slight slow-down (we are talking about micro-optimization speeds here, and async switching of tasks will be probably an order of magnitude slower than this slow-down).
