Struct wgpu::Surface

source ·
pub struct Surface<'window> { /* private fields */ }
Expand description

Handle to a presentable surface.

A Surface represents a platform-specific surface (e.g. a window) onto which rendered images may be presented. A Surface may be created with the function Instance::create_surface.

This type is unique to the Rust API of wgpu. In the WebGPU specification, GPUCanvasContext serves a similar role.

Implementations§

source§

impl Surface<'_>

source

pub fn get_capabilities(&self, adapter: &Adapter) -> SurfaceCapabilities

Returns the capabilities of the surface when used with the given adapter.

Returns specified values (see SurfaceCapabilities) if surface is incompatible with the adapter.

source

pub fn get_default_config( &self, adapter: &Adapter, width: u32, height: u32 ) -> Option<SurfaceConfiguration>

Return a default SurfaceConfiguration from width and height to use for the Surface with this adapter.

Returns None if the surface isn’t supported by this adapter

source

pub fn configure(&self, device: &Device, config: &SurfaceConfiguration)

Initializes Surface for presentation.

Panics
  • A old SurfaceTexture is still alive referencing an old surface.
  • Texture format requested is unsupported on the surface.
  • config.width or config.height is zero.
source

pub fn get_current_texture(&self) -> Result<SurfaceTexture, SurfaceError>

Returns the next texture to be presented by the swapchain for drawing.

In order to present the SurfaceTexture returned by this method, first a Queue::submit needs to be done with some work rendering to this texture. Then SurfaceTexture::present needs to be called.

If a SurfaceTexture referencing this surface is alive when the swapchain is recreated, recreating the swapchain will panic.

source

pub unsafe fn as_hal<A: HalApi, F: FnOnce(Option<&A::Surface>) -> R, R>( &mut self, hal_surface_callback: F ) -> Option<R>

Available on wgpu_core only.

Returns the inner hal Surface using a callback. The hal surface will be None if the backend type argument does not match with this wgpu Surface

Safety
  • The raw handle obtained from the hal Surface must not be manually destroyed
