Module ocp
ocp uses the pdict instead of a ctx variable for tracking context.
Description
The functions fetch the current span context from the pdict and passes it through to the oc_trace function of the same name.

Function Details
add_link/1
add_link(Link::opencensus:link()) -> boolean()
Add a Link to the list of Links in the current span.
add_time_event/1
add_time_event(TimeEvent::opencensus:annotation() | opencensus:message_event()) -> boolean()
Add an Annotation or MessageEvent to the list of TimeEvents in the current span.
add_time_event/2
add_time_event(Timestamp::wts:timestamp(), TimeEvent::opencensus:annotation() | opencensus:message_event()) -> boolean()
current_span_ctx/0
current_span_ctx() -> maybe(opencensus:span_ctx())
current_tags/0
current_tags() -> opencensus:tags()
finish_span/0
finish_span() -> boolean()

put_attribute/2
put_attribute(Key::unicode:unicode_binary(), Value::opencensus:attribute_value()) -> boolean() | {error, invalid_attribute}
