Struct Bitmap 

pub struct Bitmap { /* private fields */ }

A one-bit-per-pixel image, least-significant bit first, each row padded to a word boundary so a shift never crosses a row. Ward flattens it instead.

Implementations

impl Bitmap

pub fn zeros(width: usize, height: usize) -> Self

pub fn width(&self) -> usize

pub fn height(&self) -> usize

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

Panics unless the coordinate is inside the bitmap.

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

Panics unless the coordinate is inside the bitmap.

pub fn count_ones(&self) -> u64

Ward’s BitmapTotal. Padding is held clear, so whole words can count.

pub fn words_per_row(&self) -> usize

How many words each row occupies, padding included.

pub fn row(&self, y: usize) -> &[u64]
