Spans.

A Span is the workhorse of traces, it indicates an operation that took place over a given span of time (indicated by start_time and end_time) as part of a hierarchical trace. All spans in a given trace are bound by the use of the same Trace_id.t.

type t = Proto.Trace.span

type id = Span_id.t

type nonrec kind = Proto.Trace.span_span_kind =

| Span_kind_unspecified
| Span_kind_internal
| Span_kind_server
| Span_kind_client
| Span_kind_producer
| Span_kind_consumer

type nonrec status_code = Proto.Trace.status_status_code =

| Status_code_unset
| Status_code_ok
| Status_code_error

type nonrec status = Proto.Trace.status = {

message : string;
code : status_code;

}

val id : t -> Span_id.t

type key_value =
  string
  * [ `Int of int
    | `String of string
    | `Bool of bool
    | `Float of float
    | `None ]

create ~trace_id name creates a new span with its unique ID.

parameter trace_id
the trace this belongs to

parameter parent
parent span, if any

parameter links
list of links to other spans, each with their trace state (see w3.org)
