The Rustonomicon is the official Rust book on advanced and unsafe Rust programming, built with mdBook. It explains the details needed to write correct unsafe Rust code, assuming prior systems programming knowledge.

Use cases

• learn unsafe rust
• understand rust memory model
• write correct unsafe code in rust
• learn about raw pointers and lifetimes in rust
• deep dive into rust internals
• understand undefined behavior in rust

When to choose

• you already know Rust basics and need to write or review unsafe code
• you want the official deep reference on unsafe Rust semantics
• you are building FFI or low-level systems code in Rust

When to avoid

• you are a Rust beginner - start with The Rust Programming Language instead
• you need a complete, error-free reference - the book is explicitly a draft and incomplete
• you only write safe Rust and never touch unsafe blocks
