# Why Rust? ## Why Rust? Because we want a systems programming language that's not C. ## About this guide This guide borrows heavily from the offical [Rust Book](https://doc.rust-lang.org/book/second-edition/index.html). However, this is shortened because it is meant to be done in about three classroom hours (about one and a half solo) and altered slightly because it is aimed at high school students who have recently completed AP CS. Since this is aimed at students who are not able to install anything on school computers, we will be using [Repl.it](http://repl.it). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://jmkoni.gitbook.io/rust/master.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
