Rust Programming Tutorials, Guides & Best Practices

let file = File::open("hello.txt").unwrap();
let file = File::open("hello.txt").expect("File not found!");

This Rust cheatsheet covers the essentials you'll need while working with Rust, from basic syntax and control flow to advanced concepts like lifetimes, concurrency, and error handling. Keep this cheatsheet handy as you work with Rust to quickly recall the syntax and concepts you need.

• Each value has a unique owner.
• Ownership can be transferred, or “moved.”
• When the owner goes out of scope, the value is deallocated.

Borrowing allows you to access a value without taking ownership. This is done through references, which come in two forms: immutable and mutable. Rust’s borrowing rules ensure that data races and other concurrency issues are avoided.
