Rust编程语言是一致的，并尽最大努力避免让程序员感到惊讶。不过，和所有语言一样，锈迹仍然有其怪癖。但这些怪癖提供了一个教学机会。在本书中，你将学习一系列脑筋急转弯，挑战你对生锈的理解。通过了解自己知识中的差距，你可以在工作中做得更好，避免错误。本书中的许多谜题都来自作者自己创建软件的经验。另一些则来自Rust社区的常见问题。不管它们来自哪里，这些脑筋急转弯都很有趣，让我们面对现实：谁不喜欢一个好的谜题，对吧？
有什么比收集动态脑筋急转弯更好的方法来锻炼你的大脑和增加你的编程知识？当你通读每一个谜题并试图找出答案时，你不仅会了解Rust独特的怪癖和特性，你还会从中获得很多乐趣。
直接切入，开始使用示例代码和示例问题，包括数字和文本、阴影和内存，以及介于两者之间的所有内容。试着弄清楚为什么一个特定的程序无法编译，为什么它会产生意外的输出，或者为什么它会崩溃并以错误消息终止。一旦你运行了代码并阅读了答案，是时候用详细的解释来触及问题的核心了。了解程序为什么会产生这样的结果，并发现类似的问题可能会如何影响您在自己的程序中编写的代码，即使是在生产中。这些挑战来源于Rust社区内的讨论、现实世界的问题，甚至读者的反馈，肯定会给你带来惊喜、启发和娱乐。
你准备好体验前所未有的生锈了吗？然后磨砺你的大脑，准备迎接挑战！

Rust Brain Teasers: Exercise Your Mind
The Rust programming language is consistent and does its best to avoid surprising the programmer. Like all languages, though, Rust still has its quirks. But these quirks present a teaching opportunity. In this book, you’ll work through a series of brain teasers that will challenge your understanding of Rust. By understanding the gaps in your knowledge, you can become better at what you do and avoid mistakes. Many of the teasers in this book come from the author’s own experience creating software. Others derive from commonly asked questions in the Rust community. Regardless of their origin, these brain teasers are fun, and let’s face it: who doesn’t love a good puzzle, right?
What better way to exercise your brain and increase your Rust programming knowledge than with a collection of dynamic brain teasers? As you read through each of these puzzles and try to work out the answers, you’ll not only learn about Rust’s unique quirks and peculiarities, you’ll also have loads of fun along the way.
Dive right in and get started with example code and sample problems that cover numbers and text, shadowing and memory, and everything in between. Try to figure out why a particular program won’t compile, why it produces unexpected output, or why it panics and terminates with an error message. Once you’ve run the code and read the answer, it’s time to get to the heart of the matter with a detailed explanation. Learn why a program produced the result it did, and discover how similar issues might affect the code you write in your own programs, even in production. Sourced from engaging discussions within the Rust community, real-world problems, and even reader feedback, these challenges will certainly surprise, enlighten, and entertain you.
Are you ready to experience Rust like never before? Then sharpen your brain and get ready for a challenge!
