forked from boostorg/beast
A new function, buffers(), returns an implementation defined object which wraps a ConstBufferSequence and supports formatting to a std::ostream. The function to_string is removed, as the new implementation allows conversion to string using boost::lexical_cast on the return value of the call to buffers(). Streaming to an output stream is more efficient: no dynamic allocations are performed. Example: streambuf sb; std::cout << buffers(sb.data()) << std::endl;
