applyWhiteCfg()

void fl::anonymous_namespace{channel.cpp.hpp}::applyWhiteCfg ( CLEDController & ctrl, const ChannelOptions & options )

inline

Apply the white-channel selection from ChannelOptions to a CLEDController.

The variant alternative chooses RGB-only / RGBW / RGBWW without forcing every call site to duplicate the dispatch.

        // Empty alternative (or default-constructed) → plain RGB.
        ctrl.clearWhiteChannel();
