Yeah, there are some pretty solid crates coming up. Obviously Tokio as a runtime, Rayon for parallel iterators,and the whole Async Std crate. Rayon is a good example of a crate that helps add concurrency without much headache for embarrassingly parallel operations. Even still, even in languages with built-in runtimes and GC like GO, it is very easy to create deadlocks/livelocks. Programmers intuitions of concurrency are generally wrong, and the correct intuitions are complex. I don't know how we make concurrency easy. I do like Futures however, they provide a nice abstraction over threads.
