Required Methods

unsafe fn exit(self, queue: <Self::A as Api>::Queue)

Exit connection to this logical device.

unsafe fn create_buffer( &self, desc: &BufferDescriptor<'_> ) -> Result<<Self::A as Api>::Buffer, DeviceError>

Creates a new buffer.

The initial usage is BufferUses::empty().

unsafe fn destroy_buffer(&self, buffer: <Self::A as Api>::Buffer)

unsafe fn destroy_query_set(&self, set: <Self::A as Api>::QuerySet)

unsafe fn create_fence(&self) -> Result<<Self::A as Api>::Fence, DeviceError>

unsafe fn destroy_fence(&self, fence: <Self::A as Api>::Fence)

unsafe fn get_fence_value( &self, fence: &<Self::A as Api>::Fence ) -> Result<u64, DeviceError>

unsafe fn wait( &self, fence: &<Self::A as Api>::Fence, value: u64, timeout_ms: u32 ) -> Result<bool, DeviceError>

Wait for fence to reach value.

Operations like Queue::submit can accept a Fence and a FenceValue to store in it, so you can use this wait function to wait for a given queue submission to finish execution.

The value argument must be a value that some actual operation you have already presented to the device is going to store in fence. You cannot wait for values yet to be submitted. (This restriction accommodates implementations like the vulkan backend’s FencePool that must allocate a distinct synchronization object for each fence value one is able to wait for.)

Calling wait with a lower FenceValue than fence’s current value returns immediately.

unsafe fn start_capture(&self) -> bool

unsafe fn stop_capture(&self)

unsafe fn create_acceleration_structure( &self, desc: &AccelerationStructureDescriptor<'_> ) -> Result<<Self::A as Api>::AccelerationStructure, DeviceError>
