Manual driving of a standalone render sub-app built by build_render_app.

Required Methods

fn set_frame_target( &mut self, render_textures: &RenderTextures, clear_color: Color, )

Point the render world at the frame’s output target.

Cheap: the frame target clones the textures’ views. Inserted per frame when the output rotates over multiple readback buffers.

fn render_frame( &mut self, render_textures: &mut RenderTextures, clear_color: Color, frame: &mut EvaluatedFrame, )

Extract and render one evaluated frame into render_textures.

The frame is temporarily swapped into the render world, then returned with its input data intact so its batches can be reused or rendered again. Extraction systems should only read the frame.

fn take_last_gpu_scopes(&mut self) -> Option<Vec<GpuTimerQueryResult>>

Take the GPU timer scopes recorded for the most recent processed frame (empty unless GPU timers are enabled and the device supports timestamp queries).

fn gpu_timers_supported(&self) -> bool

Whether the device supports GPU timestamp queries.

fn gpu_timers_enabled(&self) -> bool

Whether GPU timer scopes are currently being recorded.

fn set_gpu_timers_enabled(&self, on: bool)

Enable/disable GPU timer recording at runtime. While enabled, each frame pays a device poll to read the timers back.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
