3. 'impl Trait'. This provides a way to say, "Look, my return type implements 'Trait', but the actual type declaration is way to tedious to write out, and anyway, it's private. This will help a lot with cleaning up complex Tokio types. https://github.com/rust-lang/rfcs/blob/master/text/1522-cons...
At work, we use Rust, but we're avoiding using Tokio until these features land.
1. async/await. This is analogous to async/await in C# and ES6, and should make the syntax a lot nicer. https://github.com/alexcrichton/futures-await
2. Coroutines. This is the supporting technology for async/await. https://github.com/rust-lang/rfcs/blob/master/text/2033-expe...
