Struct SurfaceGpuContext

pub struct SurfaceGpuContext { /* private fields */ }

Device-bound state that can outlive a native presentation surface.

Keeping the instance and adapter here lets a suspended host discard only SurfaceAttachment while retaining the device, queue, and pipeline cache.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::SurfaceGpuContext;

assert!(std::mem::size_of::<SurfaceGpuContext>() > 0);

Implementations

impl SurfaceGpuContext

pub fn instance(&self) -> &Instance

Returns the instance that created the retained adapter and surfaces.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::SurfaceGpuContext;

fn instance(context: &SurfaceGpuContext) -> &wgpu::Instance {
    context.instance()
}

pub fn adapter(&self) -> &Adapter

Returns the adapter selected for the current presentation format.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::SurfaceGpuContext;

fn adapter(context: &SurfaceGpuContext) -> &wgpu::Adapter {
    context.adapter()
}

pub fn device(&self) -> &Device

Returns the logical device retained across surface detachments.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::SurfaceGpuContext;

fn device(context: &SurfaceGpuContext) -> &wgpu::Device {
    context.device()
}

pub fn queue(&self) -> &Queue

Returns the submission queue paired with Self::device.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::SurfaceGpuContext;

fn queue(context: &SurfaceGpuContext) -> &wgpu::Queue {
    context.queue()
}

pub fn pipelines(&self) -> &PipelineCache

Returns pipelines compiled for Self::format.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::{PipelineCache, SurfaceGpuContext};

fn pipelines(context: &SurfaceGpuContext) -> &PipelineCache {
    context.pipelines()
}

pub fn format(&self) -> TextureFormat

Returns the texture format baked into the retained pipeline cache.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::SurfaceGpuContext;

fn format(context: &SurfaceGpuContext) -> wgpu::TextureFormat {
    context.format()
}

pub fn adapter_info(&self) -> AdapterInfo

Queries descriptive information for the retained adapter.

Examples

use ailloli_ui_render_wgpu::pipeline_cache::SurfaceGpuContext;

fn name(context: &SurfaceGpuContext) -> String {
    context.adapter_info().name
}
