Struct Symmetric2DMatrix

pub struct Symmetric2DMatrix { /* private fields */ }

A matrix of boolean values, where matrix[x, y] == matrix[y, x]

Implementations

impl Symmetric2DMatrix

pub const fn new() -> Self

Creates an empty matrix.

pub fn get(&self, x: usize, y: usize) -> bool

Returns the value of the matrix at position (x, y).

pub fn set(&mut self, x: usize, y: usize) -> bool

Sets the value of the matrix at position (x, y) to true. Returns true if the value at (x, y) was changed, otherwise false.

pub fn iter_row_indices(&self, y: usize) -> impl Iterator<Item = usize> + '_

Yields all indices x where self.get(x, y) is true.

pub fn raw_data(&self) -> &GrowingBitmap

Returns the backing bitmap.
