Struct LayerWork 

pub struct LayerWork {
    pub backdrop: bool,
    pub chrome: bool,
    pub chrome_tiles: Option<Vec<FineDamageRect>>,
    pub workspace: WorkspaceWork,
    pub composite: Option<FineDamageRect>,
}

The work a frame takes: which layers to rasterise, and where to composite the output.

Fields

backdrop: bool

chrome: bool

chrome_tiles: Option<Vec<FineDamageRect>>

Where the chrome is rasterised again when it is: only these tiles (chrome_damage), or the whole layer with None.

workspace: WorkspaceWork

composite: Option<FineDamageRect>

The output rect to composite again; None when the output already shows the frame.

Implementations

impl LayerWork

pub fn raster_pixels(&self, size: (u32, u32)) -> u64

Pixels this frame rasterises with vello, of an output of size.

pub fn composite_pixels(&self) -> u64

Pixels this frame composites.

pub fn rasterises_nothing(&self) -> bool

The layer textures already hold the frame: nothing to rasterise.

Trait Implementations

impl Clone for LayerWork

fn clone(&self) -> LayerWork

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerWork

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

Formats the value using the given formatter.

impl PartialEq for LayerWork

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
