How to create a Three Dimensional Vector in Rust - Step by Step Examples

How to create a Three Dimensional Vector in Rust ?

Answer

To create a three-dimensional vector in Rust, you can use nested vectors.


✐ Examples

1 Create a Numeric Three-Dimensional Vector

In this example,

  1. We create a vector of vectors of vectors, representing a three-dimensional structure.
  2. We specify the dimensions of the vector using nested vectors.
  3. We assign values to the elements of the vector.

Rust Program

fn main() {
    // Step 1: Create a numeric three-dimensional vector
    let mut three_dimensional_vector: Vec<Vec<Vec<i32>>> = vec![
        vec![vec![1, 2, 3], vec![4, 5, 6], vec![7, 8, 9]],
        vec![vec![10, 11, 12], vec![13, 14, 15], vec![16, 17, 18]],
        vec![vec![19, 20, 21], vec![22, 23, 24], vec![25, 26, 27]],
    ];

    // Step 2: Print the vector
    println!("{:?}", three_dimensional_vector);
}

Output

[[[1, 2, 3], [4, 5, 6], [7, 8, 9]], [[10, 11, 12], [13, 14, 15], [16, 17, 18]], [[19, 20, 21], [22, 23, 24], [25, 26, 27]]]

2 Create a String Three-Dimensional Vector

In this example,

  1. We create a vector of vectors of vectors, representing a three-dimensional structure.
  2. We specify the dimensions of the vector using nested vectors.
  3. We assign values to the elements of the vector.

Rust Program

fn main() {
    // Step 1: Create a string three-dimensional vector
    let mut three_dimensional_vector: Vec<Vec<Vec<&str>>> = vec![
        vec![vec!["a", "b", "c"], vec!["d", "e", "f"], vec!["g", "h", "i"]],
        vec![vec!["j", "k", "l"], vec!["m", "n", "o"], vec!["p", "q", "r"]],
        vec![vec!["s", "t", "u"], vec!["v", "w", "x"], vec!["y", "z", "!"]],
    ];

    // Step 2: Print the vector
    println!("{:?}", three_dimensional_vector);
}

Output

[[["a", "b", "c"], ["d", "e", "f"], ["g", "h", "i"]], [["j", "k", "l"], ["m", "n", "o"], ["p", "q", "r"]], [["s", "t", "u"], ["v", "w", "x"], ["y", "z", "!"]]]
