Struct OpenXrExternalUiHostFrameResult

pub struct OpenXrExternalUiHostFrameResult<'a, A> {
    pub stats: VulkanRendererStats,
    pub actions: Vec<A>,
    pub input: OpenXrActionInputFrame,
    pub ui_layer: CompositionLayerQuad<'a, Vulkan>,
    pub ray_layer: Option<CompositionLayerQuad<'a, Vulkan>>,
}

Rendered UI outputs and borrowed layers ready for end_frame.

The layer values borrow the host’s swapchains; consume them before mutably borrowing the host for another frame.

Examples

use ailloli_ui_openxr::OpenXrExternalUiHostFrameResult;
fn action_count<A>(result: &OpenXrExternalUiHostFrameResult<'_, A>) -> usize { result.actions.len() }

Fields

stats: VulkanRendererStats

Renderer counters for the completed UI frame.

actions: Vec<A>

Runtime actions drained after processing the frame.

input: OpenXrActionInputFrame

Selected pointer, optional ray, and source metadata.

ui_layer: CompositionLayerQuad<'a, Vulkan>

UI quad composition layer; always present after success.

ray_layer: Option<CompositionLayerQuad<'a, Vulkan>>

Ray composition layer when overlay and a selected ray are present.

Implementations

impl<A> OpenXrExternalUiHostFrameResult<'_, A>

pub fn layer_refs(&self) -> Vec<&CompositionLayerBase<'_, Vulkan>>

Returns UI then optional ray as erased composition-layer references.

The vector length is one without a ray and two with a ray. This allocates one small vector per call.

Examples

use ailloli_ui_openxr::OpenXrExternalUiHostFrameResult;
fn layers<A>(result: &OpenXrExternalUiHostFrameResult<'_, A>) -> usize { result.layer_refs().len() }
