val create : unit -> ?now:Core.Time_ns.Span.t -> unit -> t

Creates a function for generating new request IDs and starting new requests. The generated requests will have sequential IDs starting from 0.

val finish_ : ?now:Core.Time_ns.Span.t -> t -> t

Finishes the given request and returns the finished request. This function expects a Started request, and will raise if called on a Finished request.

val id : t -> int

Returns unique ID of the request.

val span : t -> Core.Time_ns.Span.t option

Returns the duration of the given request as a Time_ns.Span.t, or None if the request is not finished.

val span_exn : t -> Core.Time_ns.Span.t

Returns the duration of a finished request ID.
