Detailed Description

The collection of functions implementing hardware accelerated updating of CRC32-C hash by processing a few (1,2,4 or 8) bytes of input.

They are grouped together in a type, so it's easier to swap their implementation by providing algo_to_use template argument to higher level functions.
