Constructors

val make : ?sign:sign -> ?days:int -> ?hours:int -> ?minutes:int -> ?seconds:int -> ?ns:int -> unit -> (t, error) result

sign defaults to `Pos.

Returns Error if any of the arguments are negative.

  • raises Out_of_range

    if the value cannot be represented even after normalization

val make_exn : ?sign:sign -> ?days:int -> ?hours:int -> ?minutes:int -> ?seconds:int -> ?ns:int -> unit -> t
val make_frac : ?sign:sign -> ?days:float -> ?hours:float -> ?minutes:float -> ?seconds:float -> ?ns:int -> unit -> (t, error_f) result

sign defaults to `Pos.

Returns Error if any of the arguments are negative.

  • raises Out_of_range

    if the value cannot be represented even after normalization

val make_frac_exn : ?sign:sign -> ?days:float -> ?hours:float -> ?minutes:float -> ?seconds:float -> ?ns:int -> unit -> t

Viewer

val view : t -> view

Pretty printing

val pp : ?format:string -> unit -> Format.formatter -> t -> unit

Pretty printing for span. * * Default format string:

{days-nz: days }{hours-nz:X hours }{mins-nz:X mins }{secs:X}{sec-frac:.X} secs

Format string specification:

        {{                      literal {
        {days:unit}             number of days
                                unit is the string used after the number to denote its unit
        {days-nz:unit}          same as above, but does not display if number is zero

        {hours:cXunit}          number of hour, sub-day
                                character 'c' before 'X' is used for padding
                                (leave out character for no padding)
                                unit is the string used after the number to denote its unit
        {hours-nz:cXunit}       same as above, but does not display if number is zero

        {mins:cXunit}           number of minutes, sub-hour
                                character 'c' before 'X' is used for padding
                                (leave out character for no padding)
                                unit is the string used after the number to denote its unit
        {mins-nz:cXunit}        same as above, but does not display if number is zero

        {secs:cXunit}           number of seconds, sub-minute
                                character 'c' before 'X' is used for padding
                                (leave out character for no padding)
                                unit is the string used after the number to denote its unit
        {secs-nz:cXunit}        same as above, but does not display if number is zero

        {sec-frac:cNXunit}      fraction of second, sub-second
                                N determines the number of digits to take after decimal separator
                                if N is not specified, then the smallest number of digits required
                                after decimal separator for a lossless representation is used
                                character c is used as the decimal separator
                                unit is the string used after the number to denote its unit
        {secs-frac-nz:cNXunit}  same as above, but does not display if nanosecond count is
                                zero
