include Core_kernel.Time_ns.Span
type t = private Core_kernel.Core_int63.t

Core_int63.t is immediate on 64bit boxes and so plays nicely with the GC write barrier. Unfortunately, private Core_int63.t is necessary for the compiler to optimize uses.

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