% A 30-minute Introduction to Rust

7.

Rust is a modern systems programming language focusing on safety and speed. It accomplishes these goals by being memory safe without using garbage collection.

8.

This introduction will give you a rough idea of what Rust is like, eliding many details. It does not require prior experience with systems programming, but you may find the syntax easier if you've used a 'curly brace' programming language before, like C or JavaScript. The concepts are more important than the syntax, so don't worry if you don't get every last detail: you can read [the Guide](guide.html) to get a more complete explanation.

9.

Because this is about high-level concepts, you don't need to actually install Rust to follow along. If you'd like to anyway, check out [the homepage](http://rust-lang.org) for explanation.

10.

To show off Rust, let's talk about how easy it is to get started with Rust. Then, we'll talk about Rust's most interesting feature, **ownership**, and then discuss how it makes concurrency easier to reason about. Finally, we'll talk about how Rust breaks down the perceived dichotomy between speed and safety.
