◆ collect_result()

template<ComputeData InputType = std::vector<Kakshya::DataVariant>, ComputeData OutputType = InputType>
GpuChannelResult MayaFlux::Yantra::ShaderExecutionContext< InputType, OutputType >::collect_result ( )
inline

Collect the result of the last async dispatch.

Must be called only after ShaderFoundry::is_fence_signaled returns true for the FenceID returned by dispatch_async. Calls readback_primary and readback_aux using the element count cached by dispatch_core_async.

Returns
GpuChannelResult with primary float data and aux buffers.
