[−][src]Trait gfx_hal::window::Surface

pub trait Surface<B: Backend>: Debug + Any + Send + Sync {
    fn supports_queue_family(&self, family: &B::QueueFamily) -> bool;
    fn capabilities(
        &self, 
        physical_device: &B::PhysicalDevice
    ) -> SurfaceCapabilities;
    fn supported_formats(
        &self, 
        physical_device: &B::PhysicalDevice
    ) -> Option<Vec<Format>>;
}

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.

Examples

`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.
