The Rust curriculum
Rust is a compiled systems language whose compiler enforces ownership and borrowing rules at build time, so whole classes of memory and data-race bugs are rejected before a program ever runs. It is used for command-line tools, network services, embedded firmware and WebAssembly. This curriculum starts with syntax, variables, types, control flow and functions; the intermediate lessons cover ownership, structs, enums and pattern matching, which is where Rust differs most from other languages; the advanced lessons put collections, iterators, Result and Option to work. Every example is compiled and run with rustc 1.94 (edition 2021), and every exercise is checked against real tests.

- Rust Syntax and Your First ProgramHow a Rust program is put together: fn main, statements and semicolons, println! formatting, comments, blocks, and reading one line of input.8 min
- Variables and Mutability in RustWhy Rust variables are immutable by default, when to write let mut, how shadowing with let creates a new variable, and how const differs from let.7 min
- Data Types in RustRust's scalar and compound types: integer and float sizes, bool, char, tuples and arrays, plus casting with as and parsing numbers from input text.9 min
- Control Flow in Rust: if, loop, while and forHow Rust branches and repeats: if as an expression, loop with break values, while, for over ranges and arrays, continue, and labelled breaks.9 min
- Functions in RustHow to define and call Rust functions: typed parameters, the -> return type, returning the last expression, early return, tuples, and &str arguments.8 min
