buffer_ref

The buffer ref provides a wrapper around beast buffers to make them usable with asio dynamic_buffer v1.

template<
    typename Buffer>
struct buffer_ref

Name	Description
buffer_type	The type of the underlying buffer.
const_buffers_type	The ConstBufferSequence used to represent the readable bytes.
mutable_buffers_type	The MutableBufferSequence used to represent the writable bytes.

Name	Description
buffer_ref [constructor]	Create a buffer reference around `buffer`. — Copy the reference.
capacity	Return the maximum number of bytes, both readable and writable, that can be held without requiring an allocation.
commit	Move bytes from the output sequence to the input sequence.
consume	Remove `n` bytes from the readable byte sequence.
data	Returns a constant buffer sequence representing the readable bytes.
max_size	Return the maximum number of bytes, both readable and writable, that can ever be held.
prepare	Get a list of buffers that represents the output sequence, with the given size.
size	Returns the number of readable bytes.

v2 is current not supported, so that BOOST_ASIO_NO_DYNAMIC_BUFFER_V1 mustn't be defined.
