setExclusiveDriver() [1/2]

template<fl::Bus B>

void CFastLED::setExclusiveDriver ( )

inline

Register a single driver at a priority above the platform default (compile-time TU-linking variant).

Post-#2428 the default build does NOT auto-register every driver — only the platform-default driver TU links (via the legacy clockless controller's Phase 5b pre-bind). This template provides the opt-in path to add another driver and have it win priority dispatch.

Naming BusTraits<B>::instancePtr() in the body is the ODR-use that links the driver TU; the registration with the manager happens at kExclusivePriority (a value above any platform default).

Must be called before addLeds<> / FastLED.add() so newly- constructed channels see the override during driver resolution. Legacy clockless controllers that already pre-bound to the platform default via Phase 5b will continue to use that pre-bind.

Template Parameters

B	Bus identifier. The caller must have the per-driver bus_traits.h visible at the call site (which provides the BusTraits<B> specialization).
