Struct LayerPlan 

pub struct LayerPlan {
    pub begin_index: usize,
    pub end_index: usize,
    pub origin: [u32; 2],
    pub size: [u32; 2],
    pub parameters: [[[f32; 4]; 6]; 4],
    pub blur_radius: f32,
    pub blur_size: [u32; 2],
    pub revision: Arc<[u64]>,
    pub reusable: bool,
}

Checked capture plan, independent of the GPU backend.

Fields

begin_index: usize

Begin marker index in Scene::layer_boundaries.

end_index: usize

End marker index in Scene::layer_boundaries.

origin: [u32; 2]

Source rectangle origin.

size: [u32; 2]

Physical texture extent.

parameters: [[[f32; 4]; 6]; 4]

Clear, composition, horizontal and vertical blur blocks (six float4 each).

blur_radius: f32

Device-pixel Gaussian support radius; zero skips filter passes.

blur_size: [u32; 2]

Horizontal and vertical filter target extent.

revision: Arc<[u64]>

Exact immutable command identities; preserved by Scene::replay.

reusable: bool

Live external content cannot use retained filtered results.

Implementations

impl LayerPlan

pub fn needs_blur(&self, previous: Option<&Self>) -> bool

Whether the two Gaussian passes must run for this frame. Raw child pixels can survive radius edits, but filtered pixels must match the current radius.

pub fn matches(&self, previous: &Self) -> bool

Whether a previous raw capture is safe to reuse. Own opacity/color filters are evaluated at composition and do not invalidate the raw child pixels.

Trait Implementations

impl Clone for LayerPlan

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 LayerPlan

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

Formats the value using the given formatter.
