all the boolean operations on character sets become bitwise operations: intersection is AND, union is OR, complement is NOT. checking if a byte belongs to a set is a single bit test. checking if two sets are disjoint is AND followed by comparing to zero. these are all constant-time operations, and on AVX2 each one is a single instruction over the full 256 bits.，这一点在新收录的资料中也有详细论述
