template<typename Func >

output_type MayaFlux::Yantra::TemporalTransformer< InputType, OutputType >::apply_per_channel ( input_type &  input, Func &&  func  )

inlineprivate

Extracts per-channel spans, applies func to each, and reconstructs.

Template Parameters

Func	Callable matching either void(std::span<double>) for same-size operations or std::vector<double>(std::span<const double>) for operations that may resize the channel.

In-place: results are copied back into the original channel spans of input. Out-of-place: input is not mutated.
