Required Associated Types

type A: Api

Required Methods

unsafe fn init(desc: &InstanceDescriptor<'_>) -> Result<Self, InstanceError>

unsafe fn create_surface( &self, display_handle: RawDisplayHandle, window_handle: RawWindowHandle, ) -> Result<<Self::A as Api>::Surface, InstanceError>

unsafe fn enumerate_adapters( &self, surface_hint: Option<&<Self::A as Api>::Surface>, ) -> Vec<ExposedAdapter<Self::A>>

surface_hint is only used by the GLES backend targeting WebGL2
