Module Tracing_probes.EventSource

Represents a pre-computed event header that can be quickly written along with a hardware timestamp into the global trace.

Sourcetype t
Sourceval create_duration : arg_types:Tracing_zero.Writer.Arg_types.t -> category:string -> name:string -> t * t

Sourceval create_duration_end : arg_types:Tracing_zero.Writer.Arg_types.t -> category:string -> name:string -> t

Create duration end event with arguments.

Sourceval create_duration_instant : arg_types:Tracing_zero.Writer.Arg_types.t -> category:string -> name:string -> t
