Practice Rust with challenging examples, exercises and projects

This book was designed for easily diving into and getting skilled with Rust It's very easy to use. All you need to do is to make each exercise compile without ERRORS and Panics!

• https://practice.rs

Part of our examples and exercises are borrowed fromRust By Example, thanks for your great works!

Although they are so awesome, we have our own secret weapons :)

• There are three parts in each chapter: examples, exercises and practices

• Besides examples, we havea lot of exercises, you can Read, Edit and Run them ONLINE

• Covering nearly all aspects of Rust, such as async/await, threads, sync primitives, optimizing, standard libraries, tool chain, data structures and algorithms etc.

• Every exercise has its own solutions

• The overall difficulties are a bit higher and from easy to super hard: easy 🌟 medium 🌟🌟 hard 🌟🌟🌟 super hard 🌟🌟🌟🌟

What we want to do is fill in the gap between learning and getting started with real projects.

Thanks to all of ourcontributors!

🏆 Special thanks to our English editor:

We usemdbook building our exercises. You can run locally with below steps:

• Clone the repo

$ git clone https://github.com/sunface/rust-by-practice

• Install mdbook using Cargo

$ cargo install mdbook

• For Book in English

$cd rust-by-practice&& mdbook serve en/

• For Book in Chinese

$cd rust-by-practice&& mdbook serve zh-CN/

🌟🌟🌟 Tuple struct looks similar to tuples, it has added meaning the struct name provides but has no named fields. It's useful when you want give the whole tuple a name, but don't care the fields's names.

// fix the error and fill the blanksstructColor(i32,i32,i32);structPoint(i32,i32,i32);fnmain(){let v =Point(___, ___, ___);check_color(v);}fncheck_color(p:Color){let(x, _, _) = p;assert_eq!(x,0);assert_eq!(p.1,127);assert_eq!(___,255);}

🌟🌟 Within the destructuring of a single variable, both by-move and by-reference pattern bindings can be used at the same time. Doing this will result in a partial move of the variable, which means that parts of the variable will be moved while other parts stay. In such a case, the parent variable cannot be used afterwards as a whole, however the parts that are only referenced (and not moved) can still be used.

// fix errors to make it work#[derive(Debug)]structFile{name:String,data:String,}fnmain(){let f =File{name:String::from("readme.md"),data:"Rust By Practice".to_string()};let _name = f.name;// ONLY modify this lineprintln!("{}, {}, {:?}",f.name, f.data, f);}

🌟🌟 A match guard is an additional if condition specified after the pattern in a match arm that must also match, along with the pattern matching, for that arm to be chosen.

// fill in the blank to make the code work, `split` MUST be usedfnmain(){let num =Some(4);let split =5;match num{Some(x) __ =>assert!(x < split),Some(x) =>assert!(x >= split),None =>(),}}
