Tokio/futures is going to be the "blessed" way of doing async IO (the way its done in server side apps). That should be ready sometime this year. It won't be in the stdlib but it will be integrated with most of the I/O related libraries in the ecosystem and the Rust team is involved in making it happen. It seems like you're talking specifically about async I/O here? Because Rust does have parallel programming primitives both in the stdlib and in the form of libraries like rayon and crossbeam. Rayon, in particular, is amazing for parallel programming.
