dynamic_vector_buffer::dynamic_vector_buffer (1 of 2 overloads)

Construct a dynamic buffer from a string.

dynamic_vector_buffer(
    std::vector< Elem, Allocator > & v,
    std::size_t maximum_size = (std::numeric_limits< std::size_t >::max)());

v: The vector to be used as backing storage for the dynamic buffer. Any existing data in the vector is treated as the dynamic buffer's input sequence. The object stores a reference to the vector and the user is responsible for ensuring that the vector object remains valid until the dynamic_vector_buffer object is destroyed.
maximum_size: Specifies a maximum size for the buffer, in bytes.
