Required Methods§

Source

unsafe fn open( &self, features: Features, limits: &Limits, memory_hints: &MemoryHints, ) -> Result<OpenDevice<Self::A>, DeviceError>

Source

unsafe fn texture_format_capabilities( &self, format: TextureFormat, ) -> TextureFormatCapabilities

Return the set of supported capabilities for a texture format.

Source

unsafe fn surface_capabilities( &self, surface: &<Self::A as Api>::Surface, ) -> Option<SurfaceCapabilities>

Returns the capabilities of working with a specified surface.

None means presentation is not supported for it.

Source

unsafe fn get_presentation_timestamp(&self) -> PresentationTimestamp

Creates a PresentationTimestamp using the adapter’s WSI.

Source

fn get_ordered_buffer_usages(&self) -> BufferUses

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is ordered, then if the buffer state doesn’t change between draw calls, there are no barriers needed for synchronization.

Source

fn get_ordered_texture_usages(&self) -> TextureUses

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is ordered, then if the buffer state doesn’t change between draw calls, there are no barriers needed for synchronization.
