  ?attrs:
    (string * [< `Bool of bool | `Int of int | `None | `String of string ])

Sync emitter.

This instructs the collector to forward the spans to some backend at a later point.

NOTE be careful not to call this inside a Gc alarm, as it can cause deadlocks.

type scope = {

trace_id : Trace_id.t;
span_id : Span_id.t;
mutable events : Event.t list;
mutable attrs : Span.key_value list;

}

Scope to be used with with_.

val add_event : scope -> (unit -> 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 -> 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.

val with_ : 
  ?trace_state:string ->
  ?service_name:string ->
  ?attrs:(string * value) list ->

  ?scope:scope ->
  ?links:(Trace_id.t * Span_id.t * string) list ->

Sync span guard.

NOTE be careful not to call this inside a Gc alarm, as it can cause deadlocks.
