Rust Guides

Three-level Rust reference. Start where you are — beginner basics, mid-level abstractions, or advanced systems work.

3 levels Up to date with Rust 1.84+

Beginner

Variables, types, ownership basics, control flow, functions, structs, enums, and your first taste of error handling.

Traits, generics, lifetimes, iterators, closures, modules, smart pointers, and idiomatic error handling.

Async/await, Send/Sync, unsafe Rust, macros, FFI, zero-cost abstractions, and performance tuning.
