Is Future::race
in async_std equivalent to select!
in Tokio?
If yes, why does Tokio implement it by macro, while async_std implements it by normal method?

It does seem to be equivalent, yes. One reason why select!()
might be a macro is that it isn't limited to 2 futures, so it can wait for one of any number of futures.
The tokio::select!
macro can do a lot more things than the race
method can.
