## Detailed Description

Represents the region of a capture group.

This is basically for caching purpose. re_registers have similar concepts (beg and end) but they are in ptrdiff_t*. In order for us to implement MatchData#offset that info has to be converted to offset integers. This is the struct to hold such things.
