# SpanExporter describes a duck type. It is not required to subclass this
# class to provide an implementation of SpanExporter, provided the interface is
# satisfied. SpanExporter allows different tracing services to export
# recorded data for sampled spans in their own format.
#
# To export data an exporter MUST be registered to the {TracerProvider} using
# a {SpanProcessor} implementation.
