Tracing levels.

This is similar to log levels in, say, Logs. In a thoroughly instrumented program, there will be a lot of spans, and enabling them all in production might slow down the application or overwhelm the tracing system; yet they might be useful in debug situations.

since 0.7

type t =

| Error
(*
Only errors
*)
| Warning
(*
Warnings
*)
| Info
| Debug1
(*
Least verbose debugging level
*)
| Debug2
(*
Intermediate verbosity debugging level
*)
| Debug3
(*
Maximum verbosity debugging level
*)
| Trace
(*
Enable everything (default level)
*)

Level of tracing. These levels are in increasing order, i.e if level Debug1 is enabled, everything below it (Error, Warning, Info, etc.) are also enabled.
