[−][src]Struct amadeus::source::serde::_internal::ser::Impossible
Helper type for implementing a Serializer
that does not support
serializing one of the compound types.
This type cannot be instantiated, but implements every one of the traits
corresponding to the Serializer
compound types: SerializeSeq
,
SerializeTuple
, SerializeTupleStruct
, SerializeTupleVariant
,
SerializeMap
, SerializeStruct
, and SerializeStructVariant
.
impl Serializer for MySerializer { type Ok = (); type Error = Error; type SerializeSeq = Impossible<(), Error>; /* other associated types */ /// This data format does not support serializing sequences. fn serialize_seq(self, len: Option<usize>) -> Result<Self::SerializeSeq, Error> { // Given Impossible cannot be instantiated, the only // thing we can do here is to return an error. Err(...) } /* other Serializer methods */ }
