Detailed Description

“template<typename _CharT, typename _Traits =

std::char_traits<_CharT>>
class std::basic_string_view< _CharT, _Traits >“A non-owning reference to a string.

Template Parameters

_CharT Type of character
_Traits Traits for character type, defaults to char_traits<_CharT>.

A basic_string_view looks like this:

  _CharT*    _M_str
  size_t     _M_len
