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 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 to_int63_ns : t -> Core__.Import.Int63.t

Fast, implemented as the identity function.

val of_int63_ns : Core__.Import.Int63.t -> t

Somewhat fast, implemented as a range check.

val to_int_ns : t -> int

Will raise on 32-bit platforms with spans corresponding to contemporary now. Consider to_int63_ns instead.

val of_int_ns : int -> t
val to_proportional_float : t -> float

The only condition to_proportional_float is supposed to satisfy is that for all t1, t2 : t: to_proportional_float t1 /. to_proportional_float t2 = t1 // t2.

Span.Option.t is like Span.t option, except that the value is immediate on architectures where Int63.t is immediate. This module should mainly be used to avoid allocations.
