pub struct ImageView<'a> {
pub data: &'a [u8],
pub width: usize,
pub height: usize,
}Expand description
A borrowed, non-owning view into a row-major u8 grayscale image.
ImageView does not allocate or copy; it is a lightweight wrapper
around an existing byte slice. Use it to pass image data into
build_pyramid without transferring ownership.
Invariant: data.len() == width * height. The constructor
ImageView::new enforces this and returns None on mismatch.
Fields§
§data: &'a [u8]Pixel data in row-major order. Row y starts at byte
y * width.
width: usizeImage width in pixels.
height: usizeImage height in pixels.
