A library to quickly get the size and line size of your CPU caches.

Currently this crate only supports x86 CPUs, since it relies on the `CPUID` instruction, via

the [`raw_cpuid`][raw_cpuid] crate. It is a goal to support other architectures; PRs are

welcome!

Note that the library will still compile and work on non x86 architectures, but

the result of all the cache queries will be `None`.

for more information on the `CPUID` instruction.
