How to create a Two Dimensional Vector in Rust ?

Answer

To create a two-dimensional vector in Rust, you can use a vector of vectors.

✐ Examples

1 Create a Numeric Two-Dimensional Vector

In this example,

We declare a variable matrix as a vector of vectors, where each inner vector represents a row of the two-dimensional vector.
We initialize matrix with numeric vectors using the vec! macro.
Finally, we print the two-dimensional vector to standard output.

Rust Program

fn main() {
    // Step 1: Create a numeric two-dimensional vector
    let matrix: Vec<Vec<i32>> = vec![
        vec![1, 2, 3],
        vec![4, 5, 6],
        vec![7, 8, 9]
    ];
    
    // Step 2: Print the two-dimensional vector
    println!("{:?}", matrix);
}

Output

[[1, 2, 3], [4, 5, 6], [7, 8, 9]]

2 Create a String Two-Dimensional Vector

In this example,

We declare a variable matrix as a vector of vectors, where each inner vector represents a row of the two-dimensional vector.
We initialize matrix with string vectors using the vec! macro.
Finally, we print the two-dimensional vector to standard output.

Rust Program

fn main() {
    // Step 1: Create a string two-dimensional vector
    let matrix: Vec<Vec<&str>> = vec![
        vec!["a", "b", "c"],
        vec!["d", "e", "f"],
        vec!["g", "h", "i"]
    ];
    
    // Step 2: Print the two-dimensional vector
    println!("{:?}", matrix);
}

Output

[["a", "b", "c"], ["d", "e", "f"], ["g", "h", "i"]]
