Instead, I will focus on what makes Rust special. // -// Prerequisites -// ------------- -// +// 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:
+// 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. +// +// +// Getting started +// --------------- +// // 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 Rust website](https://www.rust-lang.org/). Make sure you get at least version 1.2. +// More detailed installation instructions are provided 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. -// +// This will also install `cargo`, the tool responsible for building rust projects (or *crates*). +// +// Next, fetch the Rust-101 source code from the [git repository](https://www.ralfj.de/git/rust-101.git) +// (also available [on GitHub](https://github.com/RalfJung/rust-101), and as a +// [zip archive](https://github.com/RalfJung/rust-101/archive/master.zip) in case you don't have git installed). +// +// There is a workspace prepared for you in the `workspace` folder. I suggest you copy this +// folder somewhere else. 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 will succeed.) + // Course Content // -------------- // -// The actual course is in the partXX.rs files. I suggest you get started with -// [the first part](part00.html), or jump directly to where you left off: +// Open `your-workspace/src/part00.rs` in your favorite editor, and follow the link below for +// the explanations and exercises.
