Experiment Introduction

Welcome to the Rust Book experiment, and thank you for your participation! First, we want to introduce you to the new mechanics of this experiment.

1. Quizzes

The main mechanic is quizzes: each page has a few quizzes about the page's content. We have two rules about quizzes for this experiment:

  1. Take a quiz as soon as you get to it.
  2. Do not skip a quiz.

(We don't enforce these rules, but please follow them!)

Every quiz looks like the one below. Try it out by clicking "Start".

If you get a question incorrect, you can choose to either retry the quiz, or see the correct answers. We encourage you to retry the quiz until you get 100% — feel free to review the content before retrying the quiz. Note that once you see the correct answers, you cannot retry the quiz.

If you spot an issue in a question, you can submit a bug report by clicking the 🐞 icon.

2. Highlighting

Another mechanic is highlighting: you can select any piece of text, and either highlight it or leave a comment about it. Once you select some text, click the ✏️ button, and leave an optional comment.

👉 Try highlighting this text! 👈

You can use highlights to save information for yourself. You can also use highlights to give us feedback — for example, if you think a section of content is confusing, you can let us know.

Note: your highlights will disappear if we change the content that you've highlighted. Also, your highlights are stored as a cookie. If you block cookies or change browsers, then you won't see your previous highlights.

3. ...and more!

The book's content may change as you go through the experiment. We will update this page as we add new features.
