"Webb28 mars 2024 · Eh, not exactly — you can build an executor in a blue (sync) function to block until a red (async) function is done. And from a red (async) function, you can use something like tokio::task::spawn_blocking. I guess the difficulty is when you go from red to blue, back to red — because you can't make an executor inside an executor. " - Tokio new_current_thread
