Detailed Description

template<class Reader, class Input = Reader*, unsigned kSize = 256>
class unibrow::InputBuffer< Reader, Input, kSize >

Provides efficient access to encoded characters in strings. It does so by reading characters one block at a time, rather than one character at a time, which gives string implementations an opportunity to optimize the decoding.
