val none : t
val some_is_representable : t -> Base.Bool.t
For some representations of immediate options, the encodings of none
and some
overlap. For these representations, some_is_representable value = false
if value
cannot be represented as an option. For example, Int.Option
uses min_value
to represent none
. For other representations, some_is_representable
always returns true
.

value_exn (some x) = x
. value_exn none
raises. Unlike Option.value_exn
, there is no ?message
argument, so that calls to value_exn
that do not raise also do not have to allocate.
unchecked_value (some x) = x
. unchecked_value none
returns an unspecified value. unchecked_value t
is intended as an optimization of value_exn t
when is_some t
is known to be true.

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.

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
.
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.
clamp_exn t ~min ~max
returns t'
, the closest value to t

is true.
Raises if not (min <= max)
