matrix_display

Instructions

Complete the Matrix struct below.

You will need to create the new associated function which initializes the struct.

You will also need to implement the std::fmt::Display trait, so that it prints like the example in the usage.

Expected Functions and Struct

pub struct Matrix(pub Vec<Vec<i32>>);

impl Matrix {
    pub fn new(slice: &[&[i32]]) -> Self {

    }
}

use std::fmt;

impl fmt::Display for Matrix {

}

Usage

Here is a possible program to test your function

use matrix_display::*;

fn main() {
    let matrix = Matrix::new(&[&[1, 2, 3], &[4, 5, 6], &[7, 8, 9]]);
    println!("{}", matrix);
}

And it's output:

$ cargo run
(1 2 3)
(4 5 6)
(7 8 9)
$
