I was considering buying a Rust book, but aren't they almost out-of-date before they are printed given the rapid evolution of Rust?
Rust is the 1.xx series now, so I doubt that the core language will change significantly. I have a pre C++11 book here that still very useful even today. After you properly learn the core language assimilating new stuff is much easier.
Yes. We have committed to stability, so while books may not cover some new features, all code remains valid
I’ll give you two examples, one from this book and one from TRPL. This book shows you how to write to stderr directly; a few releases after it’s cutoff date, eprintln! was added to make it easy. The code in the book still works! You could just replace it with the new macro.
TRPL’s cutoff will not include the new “impl Trait” feature that will land soonish. But all of the stuff we talk about will still work, 100%. Every new language adds new things in new releases, but we take backwards compatibility very seriously!
I do understand that backward compatibility is guaranteed, i was just thinking that "best practice" can change quite a bit when major features are added. For example an old C# 2.0 book would give a very strange idea about how to write C# 7.2 code.
It’s true, but this can also happen over time without additions too, as new libraries appear, etc. fundamentals remain the same!
