Threads

One of Rust’s big promises is fearless concurrency: making it easier to write safe, concurrent programs. We haven’t seen much of that yet. All the work we’ve done so far has been single-threaded. Time to change that!

In this chapter we’ll make our ticket store multithreaded.
We’ll have the opportunity to touch most of Rust’s core concurrency features, including:

• Threads, using the std::thread module
• Message passing, using channels
• Shared state, using Arc, Mutex and RwLock
• Send and Sync, the traits that encode Rust’s concurrency guarantees

We’ll also discuss various design patterns for multithreaded systems and some of their trade-offs.
