I have used rust but I think it has another year before it really shines. 2020 is the year of Rust - async/await, tool ecosystem, various crate stability, etc is happening fast.
Rust has already shipped everything it needed to be production ready. We're just always excited for the next big thing. Two years ago it was incremental compilation, last year it was a new borrow checker, this year it's async/await, etc.
