Module `Tracing_tool_output`Source

Sourcetype t

Sourceval param : t Async.Command.Param.t

Offers configuration parameters for where to save a file and whether to serve it

Source

val write_and_view : 
  ?num_temp_strs:int ->
  t ->
  default_name:string ->
  f:(Tracing_zero.Writer.t -> 'a Async.Deferred.Or_error.t) ->
  'a Async.Deferred.Or_error.t

After f writes a trace, either hosts a Perfetto UI server for the resulting file or just saves it and prints a message about how to view the resulting trace.

It is the responsibility of f to close the writer and Perfetto may fail to load the trace if the writer isn't closed.

Sourcemodule Serve : sig ... end

Used to view existing trace files in a hosted UI
