Rust program to create a mutable slice from an integer array

Rust | Slice Example: Write a program to create a mutable slice from an integer array.
Last Updated : October 18, 2021

Problem Statement

In this program, we will create an array of integers and then we will create a mutable slice from an integer array and change the value of created slice.

Program/Source Code

The source code to create a mutable slice from an integer array is given below. The given program is compiled and executed successfully.

// Rust program to create a mutable slice 
// from an integer array

fn main(){
   let mut intArray = [56,23,12,48,67];

   MyFun(&mut intArray[2..5]);
   println!("Array: {:?}",intArray);
}

fn MyFun(slice:&mut [i32]) {
   slice[0] = 33; 
   println!("Slice: {:?}",slice);
}

Output

Slice: [33, 48, 67]
Array: [56, 23, 33, 48, 67]

Explanation

In the above program, we created two functions MyFun(), main(). The MyFun() is used to change the value in a created slice and printed the updated slice.

Here, we created an integer array intArr. After that, we sliced the array of integers from the specified index and passed it into MyFun() function. After that, we printed the array intArray.
