【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。

Most active GitHub users (by contributions).

Most active GitHub users (

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at from Tue, 06 Dec 2016 17:06:46 GMT till Wed, 06 Dec 2017 17:06:46 GMT.

Only first 1000 GitHub users according to the count of followers are taken. This is because of limitations of GitHub search. Sorting algo in pseudocode:

  .filter(user => user.followers > 1000)
