4. Rust Concurrency & Async Training

Harness Rust’s fearless concurrency model in this intensive 3-day training. Learn to write parallel and asynchronous code that is both safe and performant, using threads, channels, async/await, and the Tokio runtime. This course takes you from basic thread spawning to building high-throughput async services that handle thousands of concurrent connections.

Training Details

Duration	3 days (24 hours)
Level	Intermediate
Delivery	In-person, Live online, Hybrid
Certification	N/A

Who Is This For?

• Rust developers building concurrent or parallel applications
• Backend engineers designing high-throughput services
• Systems programmers working with multi-threaded workloads
• Developers migrating from Go, Java, or C++ concurrency models
• Anyone building network services or data pipelines in Rust

Learning Outcomes

After completing this training, you’ll be able to:

• Spawn and manage OS threads with safe data sharing
• Use channels for message passing between threads
• Protect shared state with Mutex, RwLock, and atomic types
• Write async functions with async/await and the Future trait
• Build high-performance services using the Tokio runtime
• Debug and profile concurrent Rust applications

Detailed Agenda

Day 1: Thread-Based Concurrency

Module 1: Threads and Ownership

• Spawning threads with std::thread
• Move closures and thread ownership
• JoinHandle and thread lifecycle
• Hands-on: Build a parallel file processor

Module 2: Message Passing with Channels

• mpsc channels (multi-producer, single-consumer)
• Sending data between threads safely
• Channel patterns: fan-out, pipeline, broadcast
• Hands-on: Build a producer-consumer pipeline

Module 3: Shared State Concurrency

• Mutex and RwLock for synchronized access
• Arc for shared ownership across threads
• Deadlock prevention and lock ordering
• Hands-on: Build a concurrent cache

Module 4: Atomic Types and Lock-Free Programming

• Atomic primitives (AtomicBool, AtomicUsize, etc.)
• Memory ordering (Relaxed, Acquire, Release, SeqCst)
• Compare-and-swap operations
• Hands-on: Implement a lock-free counter and flag

Day 2: Async Programming Foundations

Module 5: Futures and the Async Model

• What is a Future and how polling works
• Async/await syntax and desugaring
• Pin and Unpin explained
• Hands-on: Implement a simple future from scratch

Module 6: The Tokio Runtime

• Tokio multi-threaded and current-thread runtimes
• Task spawning with tokio::spawn
• Task scheduling and cooperative yielding
• Hands-on: Set up a Tokio application with proper runtime configuration

Module 7: Async I/O

• Async TCP and UDP with tokio::net
• Async file I/O with tokio::fs
• Buffered readers and writers
• Hands-on: Build an async TCP echo server

Module 8: Async Synchronization

• tokio::sync primitives (Mutex, RwLock, Semaphore)
• Notify and Barrier for coordination
• Watch and broadcast channels
• Hands-on: Build a rate limiter with async semaphore

Day 3: Advanced Async Patterns and Production Use

Module 9: Streams and Async Iteration

• The Stream trait and StreamExt
• Creating streams from iterators and channels
• Buffering, merging, and selecting streams
• Hands-on: Build a real-time event processing pipeline

Module 10: Error Handling in Async Code

• Propagating errors through async call chains
• Timeout and retry patterns
• Graceful shutdown with CancellationToken
• Hands-on: Add timeout, retry, and shutdown to a service

Module 11: Concurrent Task Patterns

• join!, select!, and tokio::select!
• Spawning task groups with JoinSet
• Structured concurrency patterns
• Hands-on: Build a concurrent web scraper

Module 12: Testing and Debugging Async Code

• tokio::test and async test patterns
• Tracing and tokio-console for debugging
• Profiling async task execution
• Hands-on: Add tracing and write async tests for your service

Prerequisites

• Completion of Rust Fundamentals or equivalent experience
• Solid understanding of ownership, borrowing, and lifetimes
• Experience with traits and generics
• Basic understanding of networking concepts is helpful
