I've been wanting to mess with Rust for webapps. But I've been wondering on how it performs with a lot of async operations. Is the idea that you write CPU heavy code in Rust then call the compiled blob in say a node.js app, or is the end goal to one day compete with node.js?
Async I/O is still an open question in Rust. Over the next year I expect third-party libraries to experiment heavily in this space, which will hopefully blaze a trail for a blessed solution to be uplifted into the stdlib at some point (or if not a complete solution, at least the infrastructure to make it reasonable).
