Struct ScanlineBin 

pub struct ScanlineBin { /* private fields */ }

Binary scanline container — no per-pixel coverage, just on/off spans.

Port of C++ scanline_bin. Useful for non-AA rendering or clipping masks.

Implementations

impl ScanlineBin

pub fn new() -> Self

pub fn reset(&mut self, _min_x: i32, max_x: i32)

Prepare for a new scanline with the given X range.

pub fn begin(&self) -> &[BinSpan]

Get the slice of active spans (for renderer iteration).

Trait Implementations

impl Default for ScanlineBin

fn default() -> Self

Returns the “default value” for a type.

impl Scanline for ScanlineBin

fn reset_spans(&mut self)

Prepare for a new scanline, clearing all span data.

fn add_cell(&mut self, x: i32, _cover: u32)

Add a single cell at position x with coverage cover.

fn add_span(&mut self, x: i32, len: u32, _cover: u32)

Add a horizontal span of len pixels starting at x, all with cover.

fn finalize(&mut self, y: i32)

Finalize the scanline at the given Y coordinate.

fn num_spans(&self) -> u32

Number of spans in this scanline (0 means empty).

fn y(&self) -> i32

The Y coordinate of this scanline.
