I am new to Rust but I like the language very much. I feel its a very innovative one especially with lifetimes and ownership rules. However, I do find its flaws. Rust and Golang are about tbe same age yet Golang standard library has more arsenal than Rust (to me nonetheless). I might be totally wrong and if so forgive my ignorance. I find reading and writing XML or Excel files is very tough using Rust compared to what we have in Golang.
Also one of the things I really miss is lack of updated books / tutorials.
Hope to see Rust enter top 10 programming languages in the coming years.
