Module Async_kernel__.Time_ns.Span

type t = private Core_kernel.Int63.t

t is immediate on 64bit boxes and so plays nicely with the GC write barrier. Unfortunately, private Int63.t is necessary for the compiler to optimize uses.

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.

The limits of t are chosen to allow conversion to and from float spans with microsecond precision. This property supports Core.Timing_wheel_float in particular. See also Core.Time.

Fast, implemented as the identity function.

Fast, implemented as the identity function.

val to_int_ns : t ‑> Core_kernel__.Import.int

Will raise on 32-bit platforms. Consider to_int63_ns instead.

val of_int_ns : Core_kernel__.Import.int ‑> t
val to_proportional_float : t ‑> Core_kernel__.Import.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.
