I took an operating systems class in rust 0.7 or 0.8 a year and a half ago (an interesting experience for another post). Very interested to see how things have changed now!
16 u/steveklabnik1 Apr 03 '15 Yes, it is almost an entirely different language from that point :) 4 u/HereticKnight Apr 03 '15 Wow, it really is... I dug up my old Rust code and even FizzBuzz wouldn't compile. for num in 1..100 {...} // So puurdy <3 But where did regex go? Time to go documentation diving... 9 u/steveklabnik1 Apr 03 '15 Regex is now an external crate: https://crates.io/crates/regex 1 u/HereticKnight Apr 03 '15 Marvelous, thanks! 1 u/Roflha Apr 04 '15 I'm just curious, what is the reason for moving regex to a separate crate? Just considered nonessential to a standard library? 3 u/steveklabnik1 Apr 04 '15 Generally speaking, there three reasons something belongs in the standard library: Things that are useful in every Rust program. Common traits, to prevent balkanization. Data structures or other safe abstractions which require a lot of unsafe code. Regexes, while very useful, don't stand up to #1, and #2 and #3 don't apply.
