Module gulali::attributes

Vector attributes

Overview

Gulali uses Rust's vector standard data structure extensively. We don't reinvent yet-another data structure to keep things simple and easy to use. Gulali add the following attributes to Rust's vector:

• dim(): the number of dimensions of the vector.
• shape(): This is a list of integers indicating the size of the vector in each dimension. For a matrix with n rows and m columns, shape will be [n,m]. The length of the shape is therefore the number of dimensions, dim().
• size(): the total number of elements of the vector. This is equal to the product of the elements of shape.

Examples

// Generate a two-dimensional vector with shape [3, 3]
// filled with zeros
let matrix: Vec<Vec<i32>> = Vec::two_dim()
    .with_shape([3, 3])
    .zeros()
    .generate();

assert_eq!(matrix.dim(), 2);
assert_eq!(matrix.shape(), [3, 3]);
assert_eq!(matrix.size(), 9);
