Module Writer

The Writer module contains functions that invoke parts of Header_protocol and Short_header in order to write into the relevant (global variable) buffers in Buffer

Signature

val epoch : Profiler_epoch.t

val max_time : Core.Std.Time_ns.t

val write_new_single : Probe_id.t -> string -> Probe_type.t -> unit

These write into the header chunk

val write_new_group : Probe_id.t -> string -> Probe_type.t -> unit

val write_new_group_point : group_id:Probe_id.t -> id:Probe_id.t -> string -> Probe_id.t array -> unit

val write_timer_at : Probe_id.t -> Core.Std.Time_ns.t -> unit

These write into the short message buffer

val write_probe_at : Probe_id.t -> Core.Std.Time_ns.t -> int -> unit

val write_group_reset : Probe_id.t -> Core.Std.Time_ns.t -> unit

val dump_stats : unit -> unit

val set_at_exit_handler : [

| `Write_file of string

| `Function of (Core.Std.read, Core.Std.Iobuf.no_seek) Core.Std.Iobuf.t -> (Core.Std.read, Core.Std.Iobuf.no_seek) Core.Std.Iobuf.t list -> unit

| `Disable

] -> unit

Choose what to do with the in memory stats data at exit. The handler function is passed the header chunk and the list of data chunks. Defaults to `Write_file "stats.dat".
