// Welcome to Rust-101
// ===================
// 
// This is [Rust-101](https://www.ralfj.de/projects/rust-101/), a small *work-in-progress*
// tutorial for the [Rust language](http://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. I am writing this with a tutorial situation in mind, i.e.,
// with a teacher being around to guide students through the course and answer
// questions as they come up. However, I think they may also be useful if you
// work through them on your own, you will just have to show more initiative yourself:
// Make sure you actually type some code. It may sound stupid to manually copy code
// that you could duplicate through the clipboard, but it's actually helpful.
// If you have questions, 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 this with providing the comfort of high-level functional languages
// and guaranteeing safety (as in, the program will not crash). The vast majority of existing
// languages sacrificies one of these goals for the other. In particular, the
// first requirement rules out a garbage collector: Rust can run "mare metal".
// In fact, Rust rules out more classes of bugs than languages that achieve safety
// with a GC: Besides dangling pointers and double-free, Rust also prevents issues
// such as iterator invalidation and race conditions.
// 
// 
// Prerequisites
// -------------
// 
// You will need to have Rust installed, of course. It is available for download on
// [the Rust website](http://www.rust-lang.org/). At this point, I plan to restrict
// myself to stable Rust, so "Recommended" version is just right.
// You can find some more installation instructions in
// [the second chapter of The Book](https://doc.rust-lang.org/stable/book/installing-rust.html).
// When you are done, running `cargo build` in the root of Rust-101 should successfully compile
// all the code.
// 
// Getting the source
// ------------------
// 
// You are meant to play around with the source code of the course as you go on, so please
// fetch it from the [git repository](http://www.ralfj.de/git/rust-101.git) (also available
// [on GitHub](https://github.com/RalfJung/rust-101)).

// Course Content
// --------------
// 
// The actual course is in the partXX.rs files. The part 00-03 cover some basic of the language,
// to give you a feeling for Rust's syntax and pervasive mechanisms like pattern matching and traits.
// Parts 04-?? introduce the heart of the language, the mechanism making it different from anything
// else out there.
// 
// I suggest you get started with [the first part](part00.html), or jump directly to where you left off:
// 
// * [Part 00: Algebraic datatypes](part00.html)
// * [Part 01: Expressions, Inherent methods](part01.html)
// * [Part 02: Generic types, Traits](part02.html)
// * [Part 03: Input](part03.html)
// * [Part 04: Ownership, Borrowing](part04.html)
// * [Part 05: Clone](part05.html) (WIP)
// * [Part 06: Copy](part06.html) (WIP)
// * (to be continued)

// To actually run the code of some part (after filling in the blanks, if necessary), simply edit the `main`
// function.

fn main() {

}
