Const Generics for Type-Safe Matrix Operations

Const generics enable parameterizing types with compile-time constants, such as array or matrix dimensions.

It’s ideal for performance-critical applications like numerics, embedded systems, or games, allowing fixed-size matrices to be allocated without the overhead associated with dynamic vectors.

#![allow(unused)]
fn main() {
// Rust Bytes Issue 105: Const Generics for Type-Safe Matrix Operations

// Define the matrix struct
struct Matrix<const ROWS: usize, const COLS: usize> {
    data: [[f32; COLS]; ROWS],
}

let mat: Matrix<2, 2> = Matrix {
    data: [[1.0, 2.0], [3.0, 4.0]],
};

let value = mat.data[1][0]; // 3.0

}

You can run the code on Rust Playground.
