Rust program to create a generic function

Rust | Generics Example: Write a program to create a generic function.
Submitted by Nidhi, on November 23, 2021

Problem Solution:

In this program, we will create a generic function that can accept any type of parameter.

Program/Source Code:

The source code to create a generic function is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to create a generic function

use std::fmt::Display;

fn genric_fun<T:Display>(n1:T,n2:T){
   println!("Number1: {}",n1);
   println!("Number2: {}",n2);
}

fn main(){
   genric_fun(10 as u32, 20 as u32);
   genric_fun(10.23 as f32, 20.56 as f32);
}

Output:

Number1: 10
Number2: 20
Number1: 10.23
Number2: 20.56

Explanation:

In the above program, we created a generic function that can accept any type of parameter. The generic function is given below,

fn genric_fun<T:Display>(n1:T,n2:T){
   println!("Number1: {}",n1);
   println!("Number2: {}",n2);
}

In the main() function, we called the genric_fun() function with different types of parameters and printed them.
