operator==()

bool operator== ( view_or_value const & lhs, char const * rhs )

inline

Comparison operators for comparing string::view_or_value directly with char const*.

to_string()

template<class CharT, class Traits = std::char_traits<CharT>, class Allocator = std::allocator<CharT>>

std::basic_string< CharT, Traits, Allocator > bsoncxx::v_noabi::string::to_string	(	v_noabi::stdx::basic_string_view< CharT, Traits >	value,
		Allocator const &	alloc = Allocator() )

Convert a bsoncxx::v_noabi::stdx::string_view to a std::string.

This function may be used in place of explicit conversion to std::string, which may not be supported across all polyfill build configurations.

Example

std::string example(bsoncxx::v_noabi::stdx::string_view sv) {
  // This may not be supported depending on the polyfill library.
  // return std::string(sv);
 
  // This is supported regardless of the polyfill library.
  return bsoncxx::v_noabi::string::to_string(sv);
}
