The size of Int63 is always at least 63 bits. On a 64-bit platform it is just an int (63-bits), and on a 32-bit platform it is an int64.
Because Int63 has different sizes on 32-bit and 64-bit platforms, there are several pitfalls to be aware of:
include Int_intf.S
private int
so that the compiler can omit caml_modify when dealing with
record fields holding Int63.t
. Code should not explicitly make use of the
private
, e.g. via (i :> int)
, since such code will not compile on 32-bit
platforms.val of_int : int -> t
val to_int : t -> int option
