Module Core_kernel.Day_of_week

Provides a variant type for days of the week (Mon, Tue, etc.) and convenience functions for converting these days into other formats, like seconds since the epoch.

type t =
| Sun
| Mon
| Tue
| Wed
| Thu
| Fri
| Sat

val bin_write_t : t Bin_prot.Write.writer
val bin_read_t : t Bin_prot.Read.reader
val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

of_string s accepts three-character abbreviations and full day names with any capitalization, and strings of the integers 0-6.

include Base.Stringable.S with type t := t
val of_string : string -> t
val to_string : t -> string
val to_string_long : t -> Base.String.t

Capitalized full day names rather than all-caps 3-letter abbreviations.

val of_int_exn : Base.Int.t -> t

These use the same mapping as Unix.tm_wday: 0 <-> Sun, ... 6 <-> Sat

val of_int : Base.Int.t -> t Base.Option.t
val to_int : t -> Base.Int.t
val iso_8601_weekday_number : t -> Base.Int.t

As per ISO 8601, Mon->1, Tue->2, ... Sun->7

val shift : t -> Base.Int.t -> t

shift goes forward (or backward) the specified number of weekdays.

val num_days : from:t -> to_:t -> Base.Int.t

num_days ~from ~to_ gives the number of days that must elapse from a from to get to a to_, i.e., the smallest non-negative number i such that shift from i = to_.

val is_sun_or_sat : t -> Base.Bool.t
val all : t Base.List.t
val weekdays : t Base.List.t

Mon; Tue; Wed; Thu; Fri

val weekends : t Base.List.t

Sat; Sun
