pub struct RenderContext<'w> { /* private fields */ }
Expand description

The context with all information required to interact with the GPU.

The RenderDevice is used to create render resources and the the CommandEncoder is used to record a series of GPU operations.

Implementations§

source§

impl<'w> RenderContext<'w>

source

pub fn new( render_device: RenderDevice, adapter_info: AdapterInfo ) -> RenderContext<'w>

Creates a new RenderContext from a RenderDevice.

source

pub fn render_device(&self) -> &RenderDevice

Gets the underlying RenderDevice.

source

pub fn command_encoder(&mut self) -> &mut CommandEncoder

Gets the current CommandEncoder.

source

pub fn begin_tracked_render_pass<'a>( &'a mut self, descriptor: RenderPassDescriptor<'a, '_> ) -> TrackedRenderPass<'a>

Creates a new TrackedRenderPass for the context, configured using the provided descriptor.

source

pub fn add_command_buffer(&mut self, command_buffer: CommandBuffer)

Append a CommandBuffer to the command buffer queue.

If present, this will flush the currently unflushed CommandEncoder into a CommandBuffer into the queue before appending the provided buffer.

source

pub fn add_command_buffer_generation_task( &mut self, task: impl FnOnce(RenderDevice) -> CommandBuffer + Send + 'w )

Append a function that will generate a CommandBuffer to the command buffer queue, to be ran later.

If present, this will flush the currently unflushed CommandEncoder into a CommandBuffer into the queue before appending the provided buffer.

source

pub fn finish(self) -> Vec<CommandBuffer>

Finalizes and returns the queue of CommandBuffers.

This function will wait until all command buffer generation tasks are complete by running them in parallel (where supported).

where U: ShaderType, &'a T: for<'a> Into<U>,

source§

fn as_bind_group_shader_type(&self, _images: &RenderAssets<Image>) -> U

Return the T ShaderType for self. When used in AsBindGroup derives, it is safe to assume that all images in self exist.

impl<T> Downcast for T
where T: Any,

source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
