The goroutine-inspect tool they used looks really useful.
Does anyone know if there's a similar tool for Rust? I've had a few times in the past where I'm trying to figure out why some async application using tokio is hanging and having a similar tool would be very helpful.
There is Loom[1] (part of the Tokio project) for exhaustively testing multithreaded code. Though as far as I can tell it is designed for debugging threads, not async tasks.
