Struct pathfinding::Matrix

pub struct Matrix<C> {
    pub rows: usize,
    pub columns: usize,
    // some fields omitted
}

Matrix of an arbitrary type

Fields

rows: usize

Rows

columns: usize

Columns

Methods

impl<C: Clone> Matrix<C>

fn new(rows: usize, columns: usize, value: C) -> Matrix<C>

Create new matrix with an initial value.

fn new_square(size: usize, value: C) -> Matrix<C>

Create new square matrix with initial value.

fn fill(&mut self, value: C)

Fill with a known value.

impl<C> Matrix<C>

fn from_vec(rows: usize, columns: usize, values: Vec<C>) -> Matrix<C>

Create new matrix from vector values. The first value will be assigned to index (0, 0), the second one to index (0, 1), and so on.

Panics

This function will panic if the number of values does not correspond to the announced size.

fn square_from_vec(values: Vec<C>) -> Matrix<C>

Create new square matrix from vector values. The first value will be assigned to index (0, 0), the second one to index (0, 1), and so on.

Panics

This function will panic if the number of values is not a square number.

fn is_square(&self) -> bool

Check if a matrix is a square one.
