Struct WgpuRenderState 

pub struct WgpuRenderState {
    pub device: *const Device,
    pub render_pass_encoder: *mut c_void,
}

Selected render state data shared with callbacks

This corresponds to ImGui_ImplWGPU_RenderState in the C++ implementation. This is temporarily stored during the render_draw_data() call to allow draw callbacks to access the current render state.

Fields

device: *const Device

WGPU device for creating resources (raw pointer for lifetime flexibility)

render_pass_encoder: *mut c_void

Current render pass encoder for drawing (raw pointer for lifetime flexibility)

Implementations

impl WgpuRenderState

pub unsafe fn new(device: &Device, render_pass: &mut RenderPass<'_>) -> Self

Create a new render state from references

Safety

The caller must ensure that the device and render pass remain valid for the lifetime of this render state.

pub unsafe fn device(&self) -> &Device

Get the device reference

Safety

The caller must ensure that the device pointer is still valid.

pub unsafe fn render_pass_encoder(&mut self) -> &mut RenderPass<'_>

Get the render pass encoder reference

Safety

The caller must ensure that:

1. The render pass pointer is still valid
2. No other mutable references to the render pass exist
3. The lifetime is appropriate

This method returns a mutable reference and therefore requires &mut self. In callbacks, you typically obtain &mut WgpuRenderState by casting the raw Renderer_RenderState pointer provided by Dear ImGui.

Trait Implementations

impl Debug for WgpuRenderState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
