Expand description

§Safety

By implementing this trait, the user guarantees that the binary format serialized/deserialized by EspTypedEventSerializer and EspTypedEventDeserializer is indeed THE binary format that stands behind the source ID returned by the source method in this trait (and that other producers/consumers of the ESP IDF event loop also recognize as the binary format corresponbding to this source ID).

Providing the wrong source ID for a binary format, or the wrong binary format for a given source ID would lead to a runtime crash, hence this trait can only be implemented unsafely, as the guarantee lies with the user and not with the compiler, that cannot enforce this contract.
