I would say they function similarly. There are quite a few internal differences. The main benefit of Rust is that futures are just regular types and don’t need a stack when idle. And the main benefit of Go is that there is only one type of function, so no coloring.

To be pedantic, in rust the runtime is referenced with a global or thread-local variable, but it’s still explicit. This means crate authors can’t spawn tasks without depending on a runtime… unless there’s been recent developments.

Sure, their implementation differs in all sorts of ways. But for the purposes of this conversation, with regards to scheduling a future without having to manually pin it up into a your call graph, they are the same.

I guess it just comes down to your definition of explicit. There's a dependency, but from a caller's perspective it's implicit. It doesn't matter though, I think the point is clear enough.
