}

Full isolated pass descriptor produced by FrameRenderPlan::build_cpu.

Bounds and origins use physical pixels. local_size_px is the allocated integer extent after snapping and budget clamping.

Examples

use ailloli_ui_render_wgpu::PlannedIsolatedPass;
let _: usize = std::mem::size_of::<PlannedIsolatedPass>();

Fields

id: OffscreenPassId

Frame-local pass identity.

source_layer_idx: usize

Index of the source scene layer.

content_bounds_px: Rect

Tight command bounds before effect inflation, in physical pixels.

render_bounds_px: Rect

Allocated and rendered bounds after effects and budget policy.

content_origin_px: [f32; 2]

Physical origin subtracted when vertices are made pass-local.

local_size_px: [u32; 2]

Offscreen allocation width and height in physical pixels.

needs_stencil: bool

Whether rounded clipping requires a stencil attachment.

clear_color: Color

Transparent or opaque clear color used before drawing content.

effects: IsolatedEffectChain

Linear effects executed before compositing.

composite: CompositeParams

Destination, opacity, and original blend contract.

parent_id: Option<OffscreenPassId>

Parent offscreen pass (if nested).

child_pass_ids: Vec<OffscreenPassId>

Child passes sampled into this pass before local content.

isolated_depth: u8

Zero-based nesting depth; root isolated passes have depth zero.

composites_to_main: bool

When true, composite into the main frame pass (root isolated only).

backdrop_blur_radius_px: f32

Backdrop blur radius (physical px); root passes only in v1.

backdrop_capture_rect_px: Option<Rect>

Region to copy from the main framebuffer before this pass (if backdrop active).

needs_backdrop_capture: bool

Whether the main framebuffer must be copied before this pass executes.

composite_blend_mode: BlendMode

Effective blend for main-pass composite (after budget downgrade).

needs_blend_dst_capture: bool

Whether non-normal blending requires a destination snapshot.

blend_capture_rect_px: Option<Rect>

Physical main-frame region copied for destination-aware blending.
