Struct RenderBundleEncoder 

pub struct RenderBundleEncoder<'a> { /* private fields */ }

Records a reusable sequence of draw calls — build via WGPUBackend::create_render_bundle_encoder, record with the same set_pipeline/set_bind_group/set_vertex_buffer/ set_index_buffer/draw/draw_indexed shape as RenderPass, then finish into a RenderBundle. Re-executing a bundle via RenderPass::execute_bundles is often cheaper than re-recording the same draws by hand every frame — worth it once you have many draw calls that don’t change pipeline/bind group/buffers from one frame to the next (static scene geometry, say).

Implementations

impl<'a> RenderBundleEncoder<'a>

pub fn set_pipeline(&mut self, pipeline: &'a RenderPipeline)

pub fn set_bind_group( &mut self, index: u32, bind_group: &'a BindGroup, offsets: &[u32], )

offsets is the dynamic-offset slice for any dynamic-offset entries in this bind group’s layout — see RenderPass::set_bind_group.

pub fn set_vertex_buffer(&mut self, slot: u32, buffer: &'a Buffer)

Binds buffer in its entirety at vertex slot slot.

pub fn set_index_buffer(&mut self, buffer: &'a Buffer, format: IndexFormat)

Binds buffer in its entirety as the index buffer.

pub fn draw(&mut self, vertices: Range<u32>, instances: Range<u32>)

pub fn draw_indexed( &mut self, indices: Range<u32>, base_vertex: i32, instances: Range<u32>, )

pub fn finish(self, label: Option<&str>) -> RenderBundle

Stops recording and returns the replayable RenderBundle.
