                【譯】Tokio 內部機制：從頭理解 Rust 非同步 I/O 框架
              
          
本文譯自 [Tokio internals: Understanding Rust's asynchronous I/O framework from the bottom up][tokio-internals]。

Thanks [David Simmons][david-simmons] for this awesome article!

[Tokio][tokio] 是 Rust 的開發框架，用於開發非同步 I/O 程式（asynchronous I/O，一種事件驅動的作法，可實現比傳統同步 I/O 更好的延伸性、效能與資源利用）。可惜的是，Tokio 過於精密的抽象設計，招致難以學習的惡名。即使我讀完教程後，依然不認為自己充分內化這些抽象層，以便推斷實際發生的事情。
從前的非同步 I/O 相關開發經驗甚至阻礙我學習 Tokio。我習慣使用作業系統提供的 selection 工具（例如 Linux epoll）當作起點，再轉移至 dispatch、state machine 等等。倘若直接從 Tokio 抽象層出發，卻沒有清楚了解 epoll_wait() 在何處及如何發生，我會覺得難以連結每個概念。Tokio 與 future-driven 的方法就好像一個黑盒子。
