        A constant buffer sequence represents a set of memory
        regions that may be used as input to an operation, such as the send
        operation of a socket.
      
        A type X meets the ConstBufferSequence requirements
        if it satisfies the requirements of Destructible (C++Std [destructible])
        and CopyConstructible (C++Std [copyconstructible]), as well
        as the additional requirements listed below.
      
        In the table below, x denotes a (possibly const) value of type
        X, and u denotes an identifier.
