Struct GpuContext 

pub struct GpuContext { /* private fields */ }

The main GPU context holding the instance, adapter, device, queue, and surface.

Implementations

impl GpuContext

pub async fn new(window: &Window) -> Result<Self>

Create a new GPU context for the given window.

This is an async operation as it requires requesting the GPU adapter and device.

Errors

Returns an error if:

• No suitable GPU adapter could be found
• The GPU device could not be requested
• The surface could not be created

pub fn resize(&mut self, width: u32, height: u32)

Resize the surface to a new size.

Call this when the window is resized.

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

Get the current surface texture for rendering.

Errors

Returns an error if the surface texture could not be acquired.

pub fn device(&self) -> &Arc<Device>

Get a reference to the GPU device.

pub fn queue(&self) -> &Arc<Queue>

Get a reference to the GPU queue.

pub fn surface_format(&self) -> TextureFormat

Get the surface texture format.

pub fn surface_size(&self) -> (u32, u32)

Get the current surface size.

pub fn adapter_info(&self) -> AdapterInfo

Get the adapter info.

pub fn create_command_encoder(&self) -> CommandEncoder

Create a command encoder for recording GPU commands.

pub fn submit<I: IntoIterator<Item = CommandBuffer>>(&self, commands: I)

Submit command buffers to the GPU queue.
