| This is the source code of the traditional Hello World program. | |
| {hello.play} | |
| `println!` is a *macro* (we'll cover them later) that prints text to the | |
| console. | |
| A binary can be generated using the rust compiler: `rustc`. | |
| ``` | |
| $ rustc hello.rs | |
| ``` | |
| `rustc` will produce a `hello` binary that can be executed. | |
| ``` | |
| $ ./hello | |
| Hello World! | |
| ``` |
