# Getting started
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
FIXME Fill this in when the installation package is finished.
|
||
|
|
|
||
|
|
## Compiling your first program
|
||
|
|
|
||
|
|
Rust program files are, by convention, given the extension `.rs`. Say
|
||
|
|
we have a file `hello.rs` containing this program:
|
||
|
|
|
||
|
|
use std;
|
||
|
|
fn main() {
|
||
|
|
std::io::println("hello world!");
|
||
|
|
}
|
||
|
|
|
||
|
|
If the Rust compiler was installed successfully, running `rustc
|
||
|
|
hello.rs` will produce a binary called `hello` (or `hello.exe`).
|
||
|
|
|
||
|
|
If you modify the program to make it invalid (for example, remove the
|
||
|
|
`use std` line), and then compile it, you'll see an error message like
|
||
|
|
this:
|
||
|
|
|
||
|
|
hello.rs:2:4: 2:20 error: unresolved modulename: std
|
||
|
|
hello.rs:2 std::io::println("hello world!");
|
||
|
|
^~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
The Rust compiler tries to provide useful information when it runs
|
||
|
|
into an error.

||
|

## Anatomy of a Rust program
|
||
|
|
|
||
|
|
FIXME say something about libs, main, modules, use
|

|
## Editing Rust code
|
||
|
|
|
||
|
|
There are Vim highlighting and indentation scrips in the Rust source
|
||
|
|
distribution under `src/etc/vim/`. An Emacs mode can be found at
|
||
|
|
`[https://github.com/marijnh/rust-mode](https://github.com/marijnh/rust-mode)`.
|
||
|
|
|
||
|
|
Other editors are not provided for yet. If you end up writing a Rust
|
||
|
|
mode for your favorite editor, let us know so that we can link to it.
