Struct Frame 

pub struct Frame {
    pub width: u32,
    pub height: u32,
    pub rgba: Vec<u8>,
}

A rendered frame: straight (un-premultiplied) RGBA8, row-major, width × height. The CPU lane composites into this; the GPU lane reads it back for a parity test. Mirrors graphview’s Rendered so a skin can move over without a shape change.

Fields

width: u32

height: u32

rgba: Vec<u8>

width * height * 4 bytes, [r, g, b, a] per pixel, not premultiplied.

Implementations

impl Frame

pub fn lit_px(&self) -> usize

Count of pixels whose alpha is non-zero — the “did it actually draw” oracle the raster emit checkpoint reports (raster.lit_px > 0).

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Frame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Frame

fn eq(&self, other: &Frame) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
