Problem Solution:

In this program, we will create a module that contains a function. Then we will import a specific function of the module using the "use" keyword.

Program/Source Code:

The source code to import a module using the "use" keyword is given below. The given program is compiled and executed successfully.

// Rust program to import a module 
// using the "use" keyword

pub mod Sample {
   pub fn sayHello(name:String) {
      println!("Hello {}",name);
   }
}

use Sample::sayHello;

fn main(){
   sayHello("Herry Potter".to_string());
}

Output:

Hello Herry Potter

Explanation:

In the above program, we created a module Sample. The Sample module contains a function sayHello() to print the message. And, we imported the sayHello() function of module Sample using the below statement.

use Sample::sayHello;

In the main() function, we called the sayHello() method with a specified string and printed the result.
