I'm merely saying Rust async is not restricted to single threaded like many other languages design their async to be, because most people coming from Node are going to assume async is always single threaded.
Most people who write their promise implementations make them Send so they work with Tokio or Async-Std.
Relax, my guy. The shitty tone isn't necessary.
EDIT: Ah, your entire history is you just arguing with people. Got it.
Rust makes no assumptions and is explicitly designed to support both single and multi threaded executors. You can have non-Send Futures.
