Interesting. I went to read a bit about it.
There is no partial deadlock detection in Go, only full deadlock
detection. It can report how long and where routines spent blocked
though, so that you can do it manually. Yes, I suspect the rust
parallelism libraries are going to be thin on debugging tools.
Also, I haven't read Christian's X10 paper carefully, but the jist is
that deadlocks are addressed by properly restricting the parallelism
constructions employed. Imposing a DAG on the parallel components
helps. Coroutines sound more subject to deadlocks than
promises/futures, or state machines. Avoiding the need for mutexes
helps.

Yes, that is the scheduler. in GNUNet utils. It's basically the same
as libevent, libuv, etc. And mio is the analogous tool for Rust :
