{"product_id":"b0gnkxy4sz","title":"C++23 Coroutines Explained: A Practical Guide to Building Fast and Scalable Asynchronous Systems","description":"\u003cp\u003eHave you ever stared at a crash dump, realized the stack trace was empty because your task was suspended, and felt the cold sweat of an unsolvable bug?\u003c\/p\u003e\n\n\u003cp\u003eI have. We all have.\u003cbr\u003e\nThe Callback Hell of the 2010s wasn't just ugly; it was dangerous. It hid logic, swallowed exceptions, and leaked memory. We tried to fix it with Threads, but the OS crushed us under context-switching overhead. We tried std::future, but it blocked our execution.\u003c\/p\u003e\n\n\u003cp\u003eThen came the Coroutine.\u003cbr\u003e\nImagine writing a network server that handles 10,000 connections on a single thread. Imagine writing a parser that pauses execution mid-stream to wait for more data, without freezing the CPU. Imagine looking at your code and seeing a straight line—Start, Wait, Finish—while the compiler secretly builds a highly optimized state machine for you.\u003c\/p\u003e\n\n\u003cp\u003eThis book is the story of that transformation. It is the bridge between the chaotic Async of the past and the structured Structured Concurrency of the future. We don't just write code; we dismantle the engine to see how the pistons fire.\u003c\/p\u003e\n\n\u003cp\u003eWhat's Inside This book is a practical, hands-on guide that builds complexity layer by layer:\u003c\/p\u003e\n\n\u003cp\u003eThe Foundation:  Deconstruct the coroutine_handle, promise_type, and Awaitable concepts. Understand exactly what happens to your stack when you type co_await. The Machinery:  Build a  lazy, move-only  Task  from scratch. Implement std::generator for synchronous sequences and std::expected for robust error handling. The Runtime:  Write your own  Work-Stealing Thread Pool  and Executor. Learn how to migrate tasks between threads without locking the entire system. The IO Layer:  Interface directly with the Linux Kernel using  io_uring . Build a server that rivals Nginx in performance using purely asynchronous syscalls. Structured Concurrency:  Implement the  Nursery Pattern  and when_all algorithms to ensure no task is ever left behind (no orphans). Optimization Secrets:  Unlock  HALO  (Heap Allocation Elision) to run coroutines on the stack. Use  PMR (Polymorphic Memory Resources)  and Arena allocators to make dynamic allocation nearly free. Debugging the Invisible:  Strategies for visualizing suspended call graphs and debugging smashed stack traces. Who It's Meant For C++ Developers  who are tired of std::thread and callbacks and want to modernize their skillset. Systems Engineers  working in Game Development, HFT (High-Frequency Trading), or Embedded Systems where every nanosecond and byte of RAM counts. Library Authors  who want to understand the dark arts of await_transform and Symmetric Transfer. Curious Minds  who aren't satisfied with it just works—you need to know  how . (Prerequisites: A solid grasp of modern C++17\/20 concepts like move semantics, templates, and lambdas.)\u003c\/p\u003e\n\n\u003cp\u003eThe compiler is ready. The standard is set. The only missing piece is  you .\u003cbr\u003e\nStop treating concurrency like black magic. Stop fearing the race condition. It’s time to take control of your execution.\u003c\/p\u003e\n\n\u003cp\u003eGrab your copy today, and start building the fastest code of your career.\u003c\/p\u003e","brand":"ANT","offers":[{"title":"Ebook","offer_id":67937902002212,"sku":"YSL40152","price":4.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/2614\/7620\/files\/81nnw_LAKKL._SY1500.jpg?v=1793278366","url":"https:\/\/booktavero.com\/products\/b0gnkxy4sz","provider":"BookTavero","version":"1.0","type":"link"}
