val elapsed : unit -> span
elapsed ()
is the number of seconds elapsed since the
beginning of the program.val tick : span -> span Note.event
tick span
is an event that occurs once in span
seconds with
the value span - span'
where span'
is the actual delay
performed by the system.
Note. Since the system may introduce delays you cannot
assume that two different calls to Brr.Time.tick
will necessarily
yield two non-simultaneous events.
val delay : span -> (unit -> unit) -> unit
delay span f
calls f
after span
seconds.type
counter
val counter : unit -> counter
counter ()
is a counter counting time from call time on.val counter_value : counter -> span
counter_value c
is the current counter value in seconds.val pp_s : Format.formatter -> span -> unit
pp_s ppf s
prints s
seconds in seconds.val pp_ms : Format.formatter -> span -> unit
pp_ms ppf s
prints s
seconds in milliseconds.val pp_mus : Format.formatter -> span -> unit
pp_mus ppf s
prints s
seconds in microseconds.
