Create a new non-modifiable buffer that represents the given string.
template< typename Elem, typename Traits, typename Allocator> const_buffers_1 buffer( const std::basic_string< Elem, Traits, Allocator > & data);
const_buffers_1(data.data(), data.size() * sizeof(Elem)).
The buffer is invalidated by any non-const operation called on the given string object.
