Callback function used for encoding and decoding.
Prior to nanopb-0.4.0, the callback was specified in per-field pb_callback_t
structure. This is still supported, but does not work inside e.g. oneof or pointer
fields. Instead, a new method allows specifying a per-message callback that
will be called for all callback fields in a message type.Content copied to clipboard
