Struct ddo::core::utils::Matrix

pub struct Matrix<T> {
    pub n: usize,
    pub m: usize,
    pub data: Vec<T>,
}

This structure implements a 2D matrix of size [ n X m ].

Example

let mut adjacency = Matrix::new_default(5, 5, None);

adjacency[(2, 2)] = Some(-5);
assert_eq!(Some(-5), adjacency[(2, 2)]);

Fields

n: usize

The number of rows

m: usize

The number of columns

data: Vec<T>

The items of the matrix

Methods

impl<T: Default + Clone> Matrix<T>

pub fn new(m: usize, n: usize) -> Self

Allows the creation of a matrix initialized with the default element

impl<T: Clone> Matrix<T>

pub fn new_default(m: usize, n: usize, item: T) -> Self

Allows the creation of a matrix initialized with the default element

Trait Implementations

impl<T: Clone> Clone for Matrix<T>

fn clone(&self) -> Matrix<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Index<(usize, usize)> for Matrix<T>

A matrix is typically an item you'll want to adress using 2D position

type Output = T

The returned type after indexing.

fn index(&self, idx: (usize, usize)) -> &Self::Output

It returns a reference to some item from the matrix at the given 2D index

impl<T> IndexMut<(usize, usize)> for Matrix<T>

fn index_mut(&mut self, idx: (usize, usize)) -> &mut Self::Output

It returns a mutable reference to some item from the matrix at the given 2D index
