```rust
|
||
|
// This is a comment, and is ignored by the compiler
|
||
|
|
||
|
// This is the main function
|
||
|
fn main() {
|
||
|
// Statements here are executed when the compiled binary is called
|
||
|
|
||
|
// Print text to the console
|
||
|
println!("Hello World!");
|
||
|
}
|
||

```
|
||
|
|
||
|
`println!` is a macro that prints text to the console.
|
||
|
|
||
|
A binary can be generated using the Rust compiler: `rustc`.
|
||
|
|
||
|
```bash
|
||
|
$ rustc hello.rs
|
||
|
```
|
||
|
|
||
|
`rustc` will produce a `hello` binary that can be executed.
|
||
|
|
||
|
```bash
|
||
|
$ ./hello
|
||
|
Hello World!
|
||
|
```
