Module Core_kernel.Char
This module extends Base.Char
, adding Identifiable
for making char identifiers and Quickcheckable
to facilitate automated testing with pseudorandom data.

Caseless
compares and hashes characters ignoring case, so that for exampleCaseless.equal 'A' 'a'
andCaseless.('a' < 'B')
aretrue
, andCaseless.Map
,Caseless.Table
lookup andCaseless.Set
membership is case-insensitive.

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.

returnst'
, the closest value tot

is true.Raises if
