Struct RenderPass 

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

A render pass, opaque — the value ActiveFrame::begin_pass/ render_context hands back for WGPUBackend. There’s no way to reach the underlying wgpu::RenderPass from outside this crate — every draw-time operation is a method here instead.

Implementations

impl<'a> RenderPass<'a>

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

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

offsets is the dynamic-offset slice for any BindingKind::dynamic_uniform_buffer/ dynamic_storage_buffer entries in this bind group’s layout, in the order they appear — empty if none.

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 draw_indirect( &mut self, indirect_buffer: &'a Buffer, indirect_offset: u64, )

Same as draw, but the vertex/instance counts come from a DrawIndirectArgs value already written into indirect_buffer at indirect_offset bytes — for a GPU-driven draw count (culling compaction, particle counts, …) the CPU never reads back.

pub fn draw_indexed_indirect( &mut self, indirect_buffer: &'a Buffer, indirect_offset: u64, )

Same as draw_indexed, but the counts come from a DrawIndexedIndirectArgs value already written into indirect_buffer at indirect_offset bytes.

pub fn execute_bundles(&mut self, bundles: &[&RenderBundle])

Replays every bundle in bundles, in order, as if their recorded commands had been issued directly against this pass.
