Type of output buffer (where MessagePack data will be written)

read ?pos buf is (nb_read, t), where nb_read is the number of bytes read from buf at pos ?pos, and t is the decoded MessagePack value.

@raise Invalid_argument "msg" when there is no valid MessagePack value to be read from buf at position pos.

read_all ?pos buf reads all messages found in buf.

• returns

  a tuple (pos, l) where pos is the new position in the buffer, and l is the list of read messages.

@raise Invalid_argument "msg" when there is no valid MessagePack value to be read from buf at position pos.

write ?pos buf msg is nb_written, the number of bytes written on buf at position ?pos. The serialization of msg have been written to buf starting at ?pos.

to_string msg is the MessagePack serialization of msg.
