Class type

Provides a variant type for representing months (e.g., Jan, Feb, or Nov) and functions for converting them to other formats (like an int).

type t =
  1. | Jan
  2. | Feb
  3. | Mar
  4. | Apr
  5. | May
  6. | Jun
  7. | Jul
  8. | Aug
  9. | Sep
  10. | Oct
  11. | Nov
  12. | Dec

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 with three capitalizations (e.g. Jan, JAN, and jan).

include Base.Stringable.S with type t := t
val of_string : string -> t
val to_string : t -> string
val all : t Base.List.t
val of_int : Base.Int.t -> t Base.Option.t

of_int i returns the ith month if i is in 1, 2, ... , 12. Otherwise it returns None.

val of_int_exn : Base.Int.t -> t
val to_int : t -> Base.Int.t

to_int t returns an int in 1, 2, ... 12.

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

shift t i goes forward (or backward) the specified number of months.
