    );
}

A trait representing an active render pass, used for recording drawing commands.

A RenderPass object is obtained from a CommandEncoder and provides methods to set pipeline state (e.g., pipeline, vertex/index buffers) and issue draw calls.

The 'pass lifetime ensures that the pass object cannot outlive the CommandEncoder that created it, and that any resources bound to it (like buffers) also live long enough.

Required Methods

fn set_pipeline(&mut self, pipeline: &'pass RenderPipelineId)

Sets the active render pipeline for subsequent draw calls.

fn set_bind_group(&mut self, index: u32, bind_group: &'pass BindGroupId)

Binds a bind group to a specific binding slot.

Arguments

• index - The bind group index (must match shader @group(N) declarations)
• bind_group - The bind group to bind

fn set_vertex_buffer(&mut self, slot: u32, buffer: &'pass BufferId, offset: u64)

Binds a vertex buffer to a specific slot.

fn set_index_buffer( &mut self, buffer: &'pass BufferId, offset: u64, index_format: IndexFormat, )

Binds an index buffer for indexed drawing.

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

Records a non-indexed draw call.

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

Records an indexed draw call.
