推薦序二
I knew Rust was a notoriously difficult programming language to learn,but it wasn''t until I read the preface to The Tao of Rust,by Alex Zhang,that I realized why it is so difficult.Alex writes:
Rust covers a wide range of knowledge,including object-oriented,funal programming,generiderlying memory ma,type systems,design patterns,and more.
Alex covers all of the topid more iao of Rust.A siext that ties all of this together will be invaluable for Rust learners.So far I''ve read a couple of chapters translated from the inal e,and I ''t wait to read more.
Rust語言難學，這已經是眾所周知的了。但是直到我看到Alex（張漢東）的《Rust編程之道》的前言時，我才明白它為什麼如此難學，Alex寫道：
“Rust 涉及的知識範圍非常廣泛，涵蓋了麵向對象、函數式、泛型、底層內存管理、類型係統、設計模式等知識。”
《Rust編程之道》一書涵蓋了所有這些主題和內容，並且將這些內容有機地聯係在一起，這對於Rust的學習者來說是非常寶貴的。我閱讀了本書部分內容的英文譯稿後，就已經迫不及待地想要閱讀更多的內容了。
