You can open a vscode tab with copilot and have it synthesize many autocompletions.

If I add your comment, a newline and the "func" keyword it does this

If I add some more context, ie "func swap(" you get

more context, "func swap(x int32) int32"

I use and like copilot, but when it comes to things like this I generally don't trust it.

I'm not very fluent with bit swapping either, so I would probably resort to google on this one.
