Struct Composite 

pub struct Composite {
    pub layer: u32,
    pub parity: PageParity,
    pub bounds: RectU16,
    pub opacity: f32,
}

Compositing a finished page onto the round’s target.

One instanced quad through the intermediate-strip pipeline: it samples source() of the page in parity and writes bounds, modulated by opacity. The page is free for reuse once the round holding this composite ends.

Fields

layer: u32

The layer being composited, indexed into CommandRecorder::layers.

parity: PageParity

The group holding the finished page.

bounds: RectU16

Where the layer lands in the round’s target, in that target’s own coordinates.

opacity: f32

Constant alpha applied while compositing, strictly between 0 and 1.

Implementations

impl Composite

pub fn source(&self) -> RectU16

The region of the page to sample, in page texels.

The layer was rendered at the page’s origin, so this is bounds moved there.

Trait Implementations

impl Clone for Composite

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Composite

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

Formats the value using the given formatter.

impl PartialEq for Composite

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

Equality operator ==.

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

Inequality operator !=.
