Struct bevy_render::renderer::RenderContext

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

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

impl<'w> RenderContext<'w>

pub fn new( render_device: RenderDevice, adapter_info: AdapterInfo, diagnostics_recorder: Option<DiagnosticsRecorder> ) -> Self

Creates a new RenderContext from a RenderDevice.

pub fn render_device(&self) -> &RenderDevice

Gets the underlying RenderDevice.

pub fn diagnostic_recorder(&self) -> impl RecordDiagnostics

Gets the diagnostics recorder, used to track elapsed time and pipeline statistics of various render and compute passes.

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

Gets the current CommandEncoder.

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.

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.

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

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.

pub fn finish( self ) -> (Vec<CommandBuffer>, RenderDevice, Option<DiagnosticsRecorder>)

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).

The CommandBuffers will be returned in the order that they were added.
