Struct MetalDevice 

pub struct MetalDevice { /* private fields */ }

A Metal device and its command queue.

Implementations

impl MetalDevice

pub fn native(&self) -> ComPtr<IFrnMetalDevice>

The native device.

Panics

Panics when the device is disposed.

Trait Implementations

impl IMetalDevice for MetalDevice

fn device(&self) -> *mut c_void

The id<MTLDevice>.

fn command_queue(&self) -> *mut c_void

The id<MTLCommandQueue>.

impl IOptionalFeatureProvider for MetalDevice

fn try_get_feature(&self, feature_type: TypeId) -> Option<Rc<dyn Any>>

The device announces itself as a Metal device, the feature that wraps the handle of an IOSurface or of a shared event for the time of its import, and its external objects feature (the import of an IOSurface and of a shared event).

impl IPlatformGraphicsContext for MetalDevice

fn ensure_current(&self) -> Rc<dyn IDisposable>

Takes the lock of the device: the UI thread and the render thread both use it, one at a time.

The device lives in the graph of the server compositor, so every caller already holds the compositor lock: the order is always the compositor lock first, then this one. Something that used the device outside the compositor would have to keep that order.

fn is_lost(&self) -> bool

Whether the context is lost and cannot be used anymore.

fn dispose(&self)

Releases the context.

fn as_any(&self) -> &dyn Any

Lets the backend recover the concrete context type.
