Function libuv::misc::hrtime

pub fn hrtime() -> u64

Returns the current high-resolution real time. This is expressed in nanoseconds. It is relative to an arbitrary time in the past. It is not related to the time of day and therefore not subject to clock drift. The primary use is for measuring performance between intervals.

Note: Not every platform can support nanosecond resolution; however, this value will always be in nanoseconds.
