/** A functor that resumes a write operation.

    An rvalue reference to an object of this type is provided by the
    write implementation to the `writer` associated with the body of
    a message being sent.

    If it is desired that the `writer` suspend the write operation (for
    example, to wait until data is ready), it can take ownership of
    the resume context using a move. Then, it returns `boost::indeterminate`
    to indicate that the write operation should suspend. Later, the calling
    code invokes the resume function and the write operation continues
    from where it left off.
