}

A Surface abstracts the surface of a native window.

Required Methods

fn supports_queue_family(&self, family: &B::QueueFamily) -> bool

Check if the queue family supports presentation to this surface.

fn capabilities( &self, physical_device: &B::PhysicalDevice, ) -> SurfaceCapabilities

Query surface capabilities for this physical device.

Use this function for configuring swapchain creation.

fn supported_formats( &self, physical_device: &B::PhysicalDevice, ) -> Option<Vec<Format>>

Query surface formats for this physical device.

This function may be slow. It’s typically used during the initialization only.

Note: technically the surface support formats may change at the point where an application needs to recreate the swapchain, e.g. when the window is moved to a different monitor.

If None is returned then the surface has no preferred format and the application may use any desired format.
