Module Core_kernel.Month
Provides a variant type for representing months (e.g., Jan
, Feb
, or Nov
) and functions for converting them to other formats (like an int).
include Bin_prot.Binable.S with type t := t
include Bin_prot.Binable.S_only_functions with type t := t
val bin_size_t : t Bin_prot.Size.sizer
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 variantt
afterwards.

val ascending : t -> t -> int
ascending
is identical tocompare
.descending x y = ascending y x
. These are intended to be mnemonic when used likeList.sort ~compare:ascending
andList.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
meanslow <= t <= high
val clamp_exn : t -> min:t -> max:t -> t
clamp_exn t ~min ~max
returnst'
, the closest value tot
such thatbetween t' ~low:min ~high:max
is true.Raises if
not (min <= max)

returns thei

val of_int_exn : Core_kernel__.Import.int -> t
val to_int : t -> Core_kernel__.Import.int
to_int t
returns an int in 1, 2, ... 12.
val shift : t -> Core_kernel__.Import.int -> t
shift t i
goes forward (or backward) the specified number of months.
