Struct OpenXrExternalHostFrame

pub struct OpenXrExternalHostFrame<'a> {
    pub context: OpenXrExternalVulkanContext<'a>,
    pub target: VulkanFrameTarget,
    pub pointer_frame: Option<&'a OpenXrPointerFrame>,
    pub frame_time_ms: u128,
}

Vulkan render target and optional UI input for one layer render.

Pointer input is omitted with None; frame time defaults to zero milliseconds.

Examples

use ailloli_ui_openxr::OpenXrExternalHostFrame;
fn elapsed(frame: &OpenXrExternalHostFrame<'_>) -> u128 { frame.frame_time_ms }

Fields

context: OpenXrExternalVulkanContext<'a>

Vulkan device/queue context for this target.

target: VulkanFrameTarget

Acquired Vulkan image and layout contract.

pointer_frame: Option<&'a OpenXrPointerFrame>

Optional complete pointer frame to route before painting.

frame_time_ms: u128

Runtime animation/paint time in milliseconds.

Implementations

impl<'a> OpenXrExternalHostFrame<'a>

pub fn new( context: OpenXrExternalVulkanContext<'a>, target: VulkanFrameTarget, ) -> Self

Creates a frame without pointer input at time zero.

Examples

use ailloli_ui_openxr::{OpenXrExternalHostFrame, OpenXrExternalVulkanContext};
use ailloli_ui_render_vulkan::VulkanFrameTarget;
fn make<'a>(context: OpenXrExternalVulkanContext<'a>, target: VulkanFrameTarget) -> OpenXrExternalHostFrame<'a> { OpenXrExternalHostFrame::new(context, target) }

pub fn with_pointer_frame( self, pointer_frame: Option<&'a OpenXrPointerFrame>, ) -> Self

Replaces the optional pointer frame.

None means no new events; it does not clear retained input state.

Examples

use ailloli_ui_openxr::{OpenXrExternalHostFrame, OpenXrPointerFrame};
fn input<'a>(frame: OpenXrExternalHostFrame<'a>, pointers: &'a OpenXrPointerFrame) -> OpenXrExternalHostFrame<'a> { frame.with_pointer_frame(Some(pointers)) }

pub fn with_frame_time_ms(self, frame_time_ms: u128) -> Self

Replaces runtime frame time in milliseconds.

Examples

use ailloli_ui_openxr::OpenXrExternalHostFrame;
fn timed<'a>(frame: OpenXrExternalHostFrame<'a>) -> OpenXrExternalHostFrame<'a> { frame.with_frame_time_ms(16) }
