Clocksource allows access to alternate clocksources like the TSC on your Intel x86 CPU. Most modern processors support 'constanttsc' allowing us to use this counter as a high resolution clock. The cost of reading this counter can be much lower than calls to 'clockgettime()' - especially on virtualized environments.
Unfortunately, this requires we use nightly rust until the asm!() macro is stabilized. We provide fallback for users on stable rust, this should allow zero-cost abstraction of clock_gettime() for stable builds without benefit of the high-performance timing.
add clocksource to your dependencies, read the code, and start using it
