* Refactor MQTT::onReceive to reduce if/else nesting * Fix missing #include <functional> * const DecodedServiceEnvelope e * Combine validDecode if statement. * Only call pb_release when validDecode. * s/ptr/channelName/ * Use reference type for deleter * Use lambda instead of bind * Document deleter * Reorder 'if's to avoid object creation * Remove unnecessary comment * Remove 'else'; simpifies #5516 --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
