I don’t know. After writing rust for a while, and slowly putting programs together, I tried Go and I feel so relived I can just write what I want in 10 seconds instead of messing with lifetimes, borrow checker and other stuff I actually don’t care about at all.
A more experienced colleague said that yes that is true, but Go can’t guarantee your code is correct, so you will spend time fixing your code also in Go. Probably true.
Right, it’s essentially the same argument as strong vs. weak typing. The weak typing proponents say JavaScript is best, because you can just write anything and you don’t need to worry about all those pesky types getting in your way. The strong typing proponents (which if it’s not obvious I am one of) point out that you can write incorrect code quickly in just about any language, but writing correct code is much harder, and the cost of correcting code increases the later the mistake is found. Errors that can’t even be written are better than errors that are found at compile time which are better than errors that are reliably caught at runtime, which are all infinitely better than errors that only randomly appear under very specific circumstances.
That is why many people switched to using TypeScript for their websites instead of JavaScript, because even though you have to spend more time putting type annotations on everything, and at the end of the day at runtime TypeScript is literally just JavaScript, the errors it lets you find at compile time instead of runtime make the effort necessary to include those types worth it. Same thing applies with Rust vs. Go. Yes it requires more thinking up front when you’re writing Rust code, and yes it might take you longer to write that code, but it’s also going to be correct code you can be confident in and not have a bunch of ticking timebombs waiting in it that you don’t even know about.
An extra 30 minutes spent having to think about a dozen lines of code, is infinitely preferable to spending 3 hours pouring over stack traces and single stepping debuggers to find that one subtle mistake you made.
That’s pretty cool. I’m not advanced enough to really understand all the ways rust is better but I read nothing but good things about it. It seems pretty universally loved.
Basically modern language with modern tooling. It’s what C++ would look like if it had been designed today. The big thing though is the abstraction of ownership and lifetimes which took C++ ideas of scopes, smart pointers, and destructors and polished them into something much more powerful. Simply put it’s possible to design APIs in Rust that are literally impossible to express in any other language, and that’s a big deal.
Added on top of that is a modern dependency management system that is severely needed in languages like C and C++, and a very powerful meta programming system that enables compile time code generation and feature selection that’s much safer and powerful than C and C++ fairly primitive pre-processor (although C++ STL does come close).
