fn serialize_bytes(&mut self, value: &[u8]) -> Result<(), Self::Error>

Enables serializers to serialize byte slices more compactly or more efficiently than other types of slices. If no efficient implementation is available, a reasonable implementation would be to forward to serialize_seq. If forwarded, the implementation looks usually just like this: rust let mut state = try!(self.serialize_seq(value)); for b in value { try!(self.serialize_seq_elt(&mut state, b)); } self.serialize_seq_end(state)
