The Unit Type

In Rust, the unit type () is a type that has exactly one value, also written as (). It is used to indicate the absence of a meaningful value and is often seen in functions that do not return a value.

In this challenge, you will implement a function that prints a message and returns the unit type.

Your task

You need to implement the function print_message() -> () that prints "Hello, Rust!" to the console and returns the unit type.

Requirements

The print_message function should print "Hello, Rust!" to the console.
The function should return the unit type ().

Example

let result = print_message();
assert_eq!(result, ());
