Struct PlannedLayer

pub struct PlannedLayer {
    pub scissor: Option<Rect>,
    pub clip_mode: ClipRenderMode,
    pub stencil_ref: Option<u32>,
    pub stencil_mask_range: Option<Range<u32>>,
    pub clip_params_none: ClipParamsGpu,
    pub clip_params_shape: Option<ClipParamsGpu>,
    pub use_clip_alpha_for_content: bool,
    pub batch_range: Range<usize>,
}

One scene layer’s GPU state snapshot inside the frame.

Examples

use ailloli_ui_render_wgpu::{clip::ClipParamsGpu, ClipRenderMode, PlannedLayer};
let layer = PlannedLayer { scissor: None, clip_mode: ClipRenderMode::Scissor,
    stencil_ref: None, stencil_mask_range: None,
    clip_params_none: ClipParamsGpu::none(), clip_params_shape: None,
    use_clip_alpha_for_content: false, batch_range: 0..0 };
assert!(layer.batch_range.is_empty());

Fields

scissor: Option<Rect>

Physical or local scissor rectangle, depending on plan scope.

clip_mode: ClipRenderMode

Effective clip mode after stencil-capability downgrade.

stencil_ref: Option<u32>

Nonzero stencil reference allocated for this layer, when applicable.

stencil_mask_range: Option<Range<u32>>

Range into FrameRenderPlan::stencil_mask_arena.

clip_params_none: ClipParamsGpu

Inactive clip uniform always available to primitive batches.

clip_params_shape: Option<ClipParamsGpu>

Primary rounded-shape uniform, if the layer has one.

use_clip_alpha_for_content: bool

Whether content also evaluates clip alpha for shader masking or stencil AA.

batch_range: Range<usize>

Range into FrameRenderPlan::batches.
