Struct Mask 

pub struct Mask { /* private fields */ }

A per-pixel coverage mask: width x height 8-bit samples with stride bytes per row (0 = not covered, 255 = fully covered). Its own grid, not the frame’s, so it stays valid when the frame is scaled.

Implementations

impl Mask

pub fn new(width: u32, height: u32, stride: u32, data: Vec<u8>) -> Option<Self>

Build a mask over data, or None if the geometry does not fit it. Dimensions reach this from a model output or a wire peer, so they are checked here once and the accessors can then index without guessing.

pub fn width(&self) -> u32

pub fn height(&self) -> u32

pub fn stride(&self) -> u32

pub fn data(&self) -> &[u8]

pub fn sample(&self, x: u32, y: u32) -> Option<u8>

Coverage at (x, y), None outside the mask.
