## What it is
A Rust tutorial written specifically for experienced C and C++ systems programmers, covering Rust by contrasting it with C++ concepts like pointers, references, and memory management. It originated as a blog series and is organized into chapters on ownership, borrowing, data types, destructuring, and more.

## Use cases
- learn Rust as a C++ programmer
- understand Rust ownership and borrowing from a C++ perspective
- map C++ pointers and references to Rust equivalents
- quickly transition from systems programming in C++ to Rust
- find explanations of Rust lifetimes using low-level intuitions
- compare Rust and C++ syntax and semantics

## When to choose
- you already know C or C++ and systems programming concepts
- you want a fast-paced tutorial that skips beginner programming basics
- you prefer learning Rust through contrasts with C++ idioms

## When to avoid
- you have no prior systems programming experience
- you need a fully up-to-date reference for the latest Rust language features
- you want a comprehensive standalone Rust book rather than a C++-focused guide

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation
- domain: tutorials, programming-languages, developer-tools
- platform: cross-platform
- tags: rust, cpp, tutorial, systems-programming
