I wouldn't go so far as to say Rust will not be production ready until we have all of this. First of all, not all apps need all of these things; especially systems-level apps don't need most of this. Second, you can easily bind to C libraries that provide these things, making Rust just as production-ready as C is.

Of course, that isn't to diminish the importance of having high-quality, safe, idiomatic implementations of these things, but that shouldn't stop you from using Rust in production.
