// Welcome to Rust-101
// ===================
// 
// This is [Rust-101](https://www.ralfj.de/projects/rust-101/), a small tutorial for
// the [Rust language](https://www.rust-lang.org/). It is intended to be an interactive,
// hands-on course: I believe the only way to *really* learn a language is to write code
// in it, so you should be coding during the course.
// 
// If you have any questions that are not answered here, check out the "Additional Resources"
// below. In particular, the IRC channel is filled with awesome people willing to help you! I spent
// lots of time there ;-)
// 
// I will assume some familiarity with programming, and hence not explain the basic
// concepts common to most languages. Instead, I will focus on what makes Rust special.
//
// Why Rust?
// ---------
// 
// When you got here, I am kind of assuming that you already decided to give Rust at
// least a look, so that I don't have to do much convincing here. But just in
// case, here's why I think Rust is worth learning:<br/>
// At this time, Rust is a language with a pretty unique set of goals. Rust aims to
// achieve C++-style control over memory and execution behavior (like, static vs. dynamic
// dispatch), which makes it possible to construct abstractions that carry no run-time
// cost. This is combined with the comfort of high-level functional languages and guaranteed
// safety (as in, the program will not crash in uncontrolled ways). The vast majority of existing
// languages sacrifices control for safety (for example, by enforcing the usage of
// a garbage collector) or vice versa. Rust can run without dynamic allocation (i.e., without
// a heap), and even without an operating system. In fact, Rust rules out more classes of bugs
// than languages that achieve safety with a garbage collector: Besides dangling pointers and
// double-free, Rust also prevents issues such as iterator invalidation and data races. Finally,
// it cleans up behind you, and deallocates resources (memory, but also file descriptors and really
// anything) when you don't need them anymore.
// 
// 
// Getting started
// ---------------
// 
// You will need to have Rust installed, of course. It is available for download on
// [the Rust website](https://www.rust-lang.org/). Make sure you get at least version 1.3.
// More detailed installation instructions are provided in
// [The Book](https://doc.rust-lang.org/stable/book/).
// This will also install `cargo`, the tool responsible for building rust projects (or *crates*).
// 
// Next, we have to prepare a workspace for you to conduct your Rust-101 work in, so that you don't
// have to start with an empty file. The easiest way is to
// [download the workspace](https://www.ralfj.de/projects/rust-101/workspace.zip)
// matching the online tutorial. Try `cargo build` in that new folder to check that compiling your
// workspace succeeds.
// (You can also execute it with `cargo run`, but you'll need to do some work before this does
// anything useful.)
//
// Alternatively, you can build the workspace from source by fetching the
// [git repository](https://www.ralfj.de/git/rust-101.git) and running `make workspace`.

// Course Content

// Open `your-workspace/src/part00.rs` in your favorite editor, and follow the link below for
// the explanations and exercises. You are ready to start. Have fun!
