But just in +// 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). 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. +// 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](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). - -// Next, fetch the Rust-101 source code from the [git repository](http://www.ralfj.de/git/rust-101.git) -// (also available [on GitHub](https://github.com/RalfJung/rust-101)). Running `cargo build` -// in the root of the repository should now succeed. -// -// I suggest you copy the folder `workspace` somewhere you like, so that you can still easily -// `git pull` updates in the main repository. After copying, try `cargo build` in the -// new location. It should complain about `part00::main()` not being found. Now you can start -// by following [Part 00](part00.html), typing in `part00.rs`. If you need to add a new file, remember to also -// add it to `main.rs` so that Rust finds it. -// -// If you do not want to copy all the code yourself, and wish to start with my code and just edit -// it, you can copy the files from `src` in this repository, to `src` in your workspace copy. +// [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 // -------------- // -// 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 04-06 introduce the heart of the language, the mechanism making it different from anything -// else out there: Ownership, borrowing, lifetimes. In part 07-??, we continue our tour through -// Rust. Finally, in parts ??-??, we implement our own version of `grep`, exhibiting useful Rust -// features as we go. -// -// You should start 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.
