Submitted by Nidhi, on October 30, 2021

Problem Solution:

In this program, we will create a static variable and then we will access created variable in a module using "use create".

Program/Source Code:

The source code to access a static variable in a module is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to access a static 
// variable in a module

pub static StaticVar: &str = "Hello World";

mod Sample {
use crate::StaticVar;

    pub fn sayHello() {
         println!("{}", StaticVar);
    }
}

fn main() {
   Sample::sayHello();
}

Output:

Hello World

Explanation:

In the above program, we created a static variable StaticVar. Then we created a module Sample, here we accessed the static variable StaticVar in module Sample.

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