CHAPTER 01 / 06
Async runtime and futures
Get started with async Rust and Tokio: understand futures, async/await, ownership, and runtime setup with small code examples.

How Tokio fits together
01 / OWNOwn or borrow dataTasks need values that can live long enough.
02 / FUTURECreate a futureasync describes work that has not run yet.
03 / AWAITYield while waiting.await lets the runtime schedule other work.
04 / CLEANUPShut down cleanlyCancel and wait for owned tasks.

CHAPTER 02 / 06
Tasks, channels, and shared state
Use tokio::spawn, select!, mpsc, and oneshot to coordinate async tasks. Examples cover shared state, timeouts, and cancellation.
CHAPTER 03 / 06
I/O and networking
Read and buffer files with Tokio, then build a TCP echo server and client. Rust examples use AsyncReadExt, AsyncWriteExt, and TcpListener.
CHAPTER 04 / 06
Graceful shutdown and testing
Shut down a Tokio TCP server gracefully and test async code with controlled time. Examples cover cancellation and task cleanup.
CHAPTER 05 / 06
Signals, processes, and concurrency
Use Tokio signals, child processes, UDP, semaphores, watch, and broadcast. Handle blocking work and non-Send tasks with Rust examples.
CHAPTER 06 / 06
Patterns, pitfalls, and feature flags
Avoid blocking the Tokio runtime, holding locks across await, and leaking tasks. Look up feature flags and async Rust patterns.
