.
val add_event : scope -> (unit -> Opentelemetry.Event.t) -> unit
Add an event to the scope. It will be aggregated into the span.
Note that this takes a function that produces an event, and will only call it if there is an instrumentation backend.
val add_attrs : scope -> (unit -> Opentelemetry.Span.key_value list) -> unit
Add an attr to the scope. It will be aggregated into the span.
Note that this takes a function that produces attributes, and will only call it if there is an instrumentation backend.
