Short lessons on Rust with code you can run in your browser. Follow a path from the basics, then practice with challenges.
Follow a path: short lessons first, then a challenge to check you can use the idea on your own.
From your first program to variables, types, conditions, loops, strings, vectors and functions, with a challenge after each topic.
Moves, references, slices, lifetimes and smart pointers: the ideas that keep Rust memory-safe without a garbage collector.
Model data with structs and enums, match on patterns, handle Option and Result, and share behavior with traits and generics.
Hash maps, iterators, closures and modules, then threads, channels and shared state.
Ten short exercises: FizzBuzz, Fibonacci, primes, strings, binary search and a bank account.
Write your first Rust program and learn what fn main and println! do.
View lesson →Declare variables with let, allow changes with mut, and use constants and shadowing.
View lesson →Work with integers, floating-point numbers, booleans and characters, and convert between them.
View lesson →Use arithmetic, comparison and logical operators, and see how integer division works.
View lesson →Create, grow, search and split text with Rust's two string types.
View lesson →Choose what runs with if, else if and else, and use if as an expression.
View lesson →Repeat code with for over a range, while with a condition, and loop with break.
View lesson →Group values with tuples and store a fixed number of items in an array.
View lesson →Learn the rule behind Rust's memory safety: every value has one owner.
