</ul>
<p>Greetings and welcome to <code>exercise.rs</code>， If you have the following problems: </p>
<ul>
<li>After learning some rust knowledge, you want make further step: do some exercises, but found unchallenging ones</li>
<li>Found nothing about rust toolchains, std, ascyn/.await topics</li>
<li>Still have no idea of what to do next, maybe you tried writing a demo /project, but... not that good or even worse: failed</li>
</ul>
<p>Then you have come to a right place: here you can find a bunch of easy to hard exercises to improve your Rust skills which cover almost every topic in Rust，this will help you fill the gap of easy-to-learn and hard-to-use.</p>
<h2 id="about-exercises"><a class="header" href="#about-exercises">About exercises</a></h2>
<ul>
<li>You can edit exercise online and then run it online too</li>
<li><strong>Your only gola is make every exercise comipile with NO ERRORS!</strong></li>
<li>difficulty level: easy: 🌟 medium: 🌟🌟 hard: 🌟🌟🌟 hell: 🌟🌟🌟🌟</li>
</ul>
<h2 id="contributing"><a class="header" href="#contributing">Contributing</a></h2>
<p>We welcome all kinds of contributors, especially ones who has precious exercises.</p>
<p>Every exercise you have contributed will be annotated with your nickname and personal link, it's time to show yourself to the world!</p>
<h2 id="learning-rust"><a class="header" href="#learning-rust">Learning Rust</a></h2>
<p>If you are a first-time Rust learner, here are some high quality learning resources :</p>
<ul>
<li><a href="https://doc.rust-lang.org/book/index.html">The Book</a> for English speakers</li>
<li><a href="https://course.rs">Rust语言圣经(The Course)</a> for Chinese speakers, it covers nearly all the topics in Rust</li>
</ul>
<h2 id="difference-to-rustlings"><a class="header" href="#difference-to-rustlings">difference to rustlings</a></h2>
<p><a href="https://github.com/rust-lang/rustlings">Rustlings</a> only contains small and easy exercises for junior rust devs. There is a big gap between learning Rust and using it in your projects.</p>
<p>Another limit for rustlings is that you have to download rustlings to local machine and compile it first before starting to learn.</p>
<h2 id="difference-to-rust-by-example"><a class="header" href="#difference-to-rust-by-example">difference to rust by example</a></h2>
<p><a href="https://doc.rust-lang.org/stable/rust-by-example/">Rust By Example</a> is an excellent online book for learning Rust，<code>exercise.rs</code> has some small advantages in :</p>
<ul>
<li>more topics and exercises，specially for the hard part of Rust，e.g lifetime、smart pointers、threads 、async/.await etc</li>
<li>difficulty from easy to hard，it will minimize the gap between learning and using in projects</li>
<li>up-to-date, e.g features which added in Rust 1.58 also have the corresponding exercises in <code>exercise.rs</code></li>
<li>Both <code>course.rs</code> and <code>exercise.rs</code> are designed according to the CS courses in college，so quliaty is the most important factor</li>
</ul>
