/*
 * upb - a minimalist implementation of protocol buffers.
 *
 * Implements a upb_sink that writes protobuf data to the binary wire format.
 *
 * For messages that have any submessages, the encoder needs a buffer
 * containing the submessage sizes, so they can be properly written at the
 * front of each message.  Note that groups do *not* have this requirement.
