### AI overview

This tutorial explains Rust's Atomic Reference Counting (Arc) for sharing ownership of data across threads. It covers reference-counted memory management, cloning, performance implications, common pitfalls such as circular references, and use cases including shared configuration and database connection pools.

### Source excerpt

Introduction: Welcome to Episode 6 of the Fearless Concurrency in Rust series! In this episode, we explore the powerful concept of ARC (Atomic Reference Counting) and its critical role in managing shared resources in multithreaded Rust programs. By leveraging ARC, developers can safely share ownership of data across threads without relying on a traditional garbage collector, enabling efficient, flexible, and scalable concurrency. What is ARC?: Understanding Atomic Reference Counting as a lightweight, manual garbage collection system.
