module Option : sig ... end

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

-1 means "less than", 0 means "equal", 1 means "greater than", and other values should not be returned

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 ~cmp: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
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 pause : Span.t ‑> unit

pause span sleeps for span time.

val interruptible_pause : Span.t ‑> [ `Ok | `Remaining of Span.t ]

interruptible_pause span sleeps for span time unless interrupted (e.g. by delivery of a signal), in which case the remaining unslept portion of time is returned.

val pause_forever : unit ‑> Core__.Import.never_returns

pause_forever sleeps indefinitely.
