Struct Evaluator 

pub struct Evaluator;

Implementations

impl Evaluator

pub fn is_active(&self) -> bool

pub fn optimal_render_extent( &self, _output_extent: [u32; 2], _quality: DlssRrQuality, ) -> Result<[u32; 2]>

Errors

Always returns an error because the native backend is unavailable.

pub unsafe fn evaluate( &self, _command_buffer: CommandBuffer, _frame: &DlssRrFrameConstants, _resources: &DlssRrResources, _quality: DlssRrQuality, ) -> Result<()>

Safety

This evaluator and its owning NGX context must remain valid until execution completes. The command buffer must be recording on the context’s device; every image and view must belong to that device, and each declared layout must match its actual state. Image ranges, formats, and extents must describe their views accurately. Before evaluation, transition all inputs (including depth and the reflection guide) to SHADER_READ_ONLY_OPTIMAL and the output to GENERAL. Evaluation leaves these layouts unchanged; this wrapper does not record layout transitions. All handles must remain valid until GPU execution completes. If dimensions or quality change, prior evaluations must have completed first.

Errors

Always returns an error because the native backend is unavailable.

pub unsafe fn shutdown(&self) -> Result<()>

Safety

All NGX GPU work must have completed before shutdown.

Errors

This stub always succeeds; the native backend can report shutdown failures.

Trait Implementations

impl Clone for Evaluator

fn clone(&self) -> Evaluator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
