For example, converting between str and String, or passing a reference instead of value to a function seems like something the compiler could figure out for me.

#RUST PROGRAMMING LANGUAGE CODE#
There are certain trade offs the compiler needs to make in order to be able to compile code within a reasonable amount of time.I find myself frequently writing code similar to option.as_ref().unwrap().borrow(), which feels icky. I wish there was some syntax sugar to cut down on the number of times I have to chain these calls together in different patterns. I find the need to unwrap(), as_ref() and borrow() a bit verbose at times.In most cases, when this happens unexpectedly, it results in someone having a bad time. A common pattern in C, C++, and even Java is for functions to return a null pointer when there’s nothing to return. Rust’s Result and Option provide a good way for dealing with functions that might return a value, or variables that might contain a value.Rust code is safe (provided you don’t use the unsafe keyword, or call out to unsafe C libraries).Traits provide modern programming abstraction without the performance penalty.

After finishing my linked list implementation, things got easier.
#RUST PROGRAMMING LANGUAGE OFFLINE#
I must have been doing something right.Īfter a bit of reading offline (and followed the very helpful “ Learning Rust With Entirely Too Many Linked Lists” book), and the concepts started to click for me. What’s amazing is that people tuned in to watch. For a while I felt like I was just banging on the keyboard trying random combinations until something stuck.
#RUST PROGRAMMING LANGUAGE HOW TO#
It took me about 8 hours to implement a linked list: I recorded two 4 hour streams of myself trying to figure out how to properly use Rc, RefCell, and Box. Trying to do that, while also explaining what I was doing to people, was uh… tricky. Things started off a bit rough: technical hiccups, stream issues, tooling problems, and I had difficulty understanding the memory paradigm at first. I’m no stranger to giving tech talks, or coding in front of an audience, but trying to learn a programming language, and explain what I was doing–live for the world to see–was something new for me. Not only would I solve them with Rust, but I decided to do it live on Twitch. I figured a good way to get to know the language was to solve all 189 problems from the “Cracking the Coding Interview” book.

Until recently, I’d written only a handful of small programs in Rust, and after reading half of “Programming Rust”, I really didn’t know Rust. I recently embarked on an effort to learn Rust properly, and I wanted to share some of my thoughts. It provides zero-cost abstractions, generics, functional features, and plenty more. Rust is a modern systems-level programming language designed with safety in mind.
