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.

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).

val quickcheck_shrinker : t Base_quickcheck.Shrinker.t
val gen_incl : t -> t -> t Base_quickcheck.Generator.t

gen_incl lower_bound upper_bound produces values between lower_bound and upper_bound, inclusive. It uses an ad hoc distribution that stresses boundary conditions more often than a uniform distribution, while still able to produce any value in the range. Raises if lower_bound > upper_bound.

val gen_uniform_incl : t -> t -> t Base_quickcheck.Generator.t

gen_uniform_incl lower_bound upper_bound produces a generator for values uniformly distributed between lower_bound and upper_bound, inclusive. Raises if lower_bound > upper_bound.

val gen_log_uniform_incl : t -> t -> t Base_quickcheck.Generator.t

gen_log_uniform_incl lower_bound upper_bound produces a generator for values between lower_bound and upper_bound, inclusive, where the number of bits used to represent the value is uniformly distributed. Raises if (lower_bound < 0) || (lower_bound > upper_bound).

val gen_log_incl : t -> t -> t Base_quickcheck.Generator.t

gen_log_incl lower_bound upper_bound is like gen_log_uniform_incl, but weighted slightly more in favor of generating lower_bound and upper_bound specifically.
