Struct Application 

pub struct Application {
    config: AppConfig,
    instance: Instance,
    adapter: Adapter,
    device: Device,
    queue: Queue,
    stage: Stage,
}

Root wgpu context.

Owns the Instance, Adapter, Device, and Queue. Construct with Application::new (async, await with a runtime such as pollster).

Headless only in M0.4 — surface attachment lands in M0.5.

Fields

config: AppConfig

instance: Instance

adapter: Adapter

device: Device

queue: Queue

stage: Stage

Implementations

impl Application

pub fn from_wgpu( instance: Instance, adapter: Adapter, device: Device, queue: Queue, config: AppConfig, ) -> Self

Adopt a pre-existing wgpu context (e.g. from eframe).

All four wgpu resources are cloned into the Application; wgpu types are Arc-backed so this is cheap. Use this instead of Application::new when integrating with an embedding host that owns the device.

pub async fn new(config: AppConfig) -> Result<Self, Error>

Construct a new Application.

Errors

• Error::AdapterUnavailable if no compatible GPU adapter is found.
• Error::DeviceRequest if device creation fails.

pub fn stage(&self) -> &Stage

Borrow the scene graph stage.

pub fn stage_mut(&mut self) -> &mut Stage

Mutably borrow the scene graph stage.

pub fn adapter_info(&self) -> AdapterInfo

Adapter info (name, backend, device type, driver).

pub fn instance(&self) -> &Instance

Borrow the wgpu instance.

pub fn adapter(&self) -> &Adapter

Borrow the wgpu adapter.

pub fn device(&self) -> &Device

Borrow the wgpu device.

pub fn queue(&self) -> &Queue

Borrow the wgpu queue.

pub fn width(&self) -> u32

Logical stage width.

pub fn height(&self) -> u32

Logical stage height.
