- Local installation / 本地安装
- Types, functions, control flow, pattern matching / 类型、函数、控制流、模式匹配
- Modules, cargo / 模块与 Cargo
- Traits, generics / Trait 与泛型

- Case studies: real-world C++ to Rust translation patterns / 案例研究：真实世界中的 C++ 到 Rust 迁移模式
We’ll not cover async Rust in this course - see the companion Async Rust Training for a full treatment of futures, executors, Pin, tokio, and production async patterns
本课程不讲解 async Rust；如需系统学习 futures、执行器、Pin、tokio 与生产级异步模式，请参考配套的 Async Rust Training

Self-Study Guide / 自学指南

This material works both as an instructor-led course and for self-study. If you’re working through it on your own, here’s how to get the most out of it:

本材料既适合讲师授课，也适合自学。如果你打算独立学习，下面的建议可以帮助你获得更好的学习效果：

Pacing recommendations / 学习节奏建议：

Chapters / 章节	Topic / 主题	Suggested Time / 建议时间	Checkpoint / 检查点
1-4	Setup, types, control flow / 环境、类型、控制流	1 day / 1 天	You can write a CLI temperature converter / 你可以写出一个命令行温度转换器
5-7	Data structures, ownership / 数据结构、所有权	1-2 days / 1-2 天	You can explain why `let s2 = s1` invalidates `s1` / 你可以解释为什么 `let s2 = s1` 会使 `s1` 失效
8-9	Modules, error handling / 模块、错误处理	1 day / 1 天	You can create a multi-file project that propagates errors with `?` / 你可以创建一个多文件项目并用 `?` 传播错误
10-12	Traits, generics, closures / Trait、泛型、闭包	1-2 days / 1-2 天	You can write a generic function with trait bounds / 你可以写出带 trait 约束的泛型函数
13-14	Concurrency, unsafe/FFI / 并发、unsafe/FFI	1 day / 1 天	You can write a thread-safe counter with `Arc<Mutex<T>>` / 你可以用 `Arc<Mutex<T>>` 写出线程安全计数器
15-16	Deep dives / 深入专题	At your own pace / 自定节奏	Reference material - read when relevant / 作为参考材料，在需要时查阅
17-19	Best practices & reference / 最佳实践与参考	At your own pace / 自定节奏	Consult as you write real code / 在实际写代码时按需查阅

How to use the exercises / 如何使用练习：

Every chapter has hands-on exercises marked with difficulty: 🟢 Starter, 🟡 Intermediate, 🔶 Challenge / 每章都包含带难度标记的动手练习：🟢 入门、🟡 中级、🔶 挑战
Always try the exercise before expanding the solution. Struggling with the borrow checker is part of learning - the compiler’s error messages are your teacher / 总是先做题，再看答案。 与借用检查器“拉扯”是学习的一部分，编译器的报错就是你的老师
If you’re stuck for more than 15 minutes, expand the solution, study it, then close it and try again from scratch / 如果卡住超过 15 分钟，就先看答案、理解思路，再关闭答案重新独立完成
The Rust Playground lets you run code without a local install / Rust Playground 允许你无需本地安装就运行代码

When you hit a wall / 遇到难点时：

Read the compiler error message carefully - Rust’s errors are exceptionally helpful / 仔细阅读编译器错误信息，Rust 的错误提示通常非常有帮助
Re-read the relevant section; concepts like ownership (ch7) often click on the second pass / 重读相关章节，像所有权这类概念常常在第二遍时真正理解
The Rust standard library docs are excellent - search for any type or method / Rust 标准库文档非常优秀，任何类型或方法都值得查阅
For async patterns, see the companion Async Rust Training / 如需学习异步模式，请参考配套的 Async Rust Training
