fn serialize_bytes(self, v: &[u8]) -> Result<()>

Raw objects.

fn serialize_none(self) -> Result<()>

None of an option is NULL.

fn serialize_some<T>(self, value: &T) -> Result<()>

where T: ?Sized + Serialize,

Some of an option is that value.

fn serialize_unit_variant( self, _name: &'static str, _variant_index: u32, variant: &'static str ) -> Result<()>

Unit variant: Enum::Name

fn serialize_newtype_struct<T>( self, _name: &'static str, value: &T ) -> Result<()>

where T: ?Sized + Serialize,

Wrapper struct: Wrap(T)

fn serialize_newtype_variant<T>( self, _name: &'static str, _variant_index: u32, variant: &'static str, value: &T ) -> Result<()>

where T: ?Sized + Serialize,

Wrapper struct in enum: Enum::Wrap(T)

fn serialize_seq(self, len: Option<usize>) -> Result<Self::SerializeSeq>

Start of a vector or other sequence.

fn serialize_tuple(self, len: usize) -> Result<Self::SerializeTuple>

Start of a tuple.

fn serialize_tuple_struct( self, _name: &'static str, len: usize ) -> Result<Self::SerializeTupleStruct>

Start of a tuple struct eg. Point(i32, i32).

fn serialize_tuple_variant( self, _name: &'static str, _variant_index: u32, variant: &'static str, len: usize ) -> Result<Self::SerializeTupleVariant>

Start of a struct variant eg. Enum::Point{ x: i32, y: i32}.

fn serialize_map(self, _len: Option<usize>) -> Result<Self::SerializeMap>

Start of a map. We require that keys must be strings.

fn serialize_struct( self, _name: &'static str, len: usize ) -> Result<Self::SerializeStruct>

Start of a struct. Collect just the values in a list.

fn serialize_struct_variant( self, _name: &'static str, _variant_index: u32, variant: &'static str, _len: usize ) -> Result<Self::SerializeStructVariant>

eg. Enum::Point { x: i32, y: i32 }

type Ok = ()

The output type produced by this Serializer during successful serialization. Most serializers that produce text or binary output should set Ok = () and serialize into an io::Write or buffer contained within the Serializer instance. Serializers that build in-memory data structures may be simplified by using Ok to propagate the data structure around.

type Error = Error

The error type when some error occurs during serialization.

type SerializeSeq = SerializeSeq<'a>

Type returned from serialize_seq for serializing the content of the sequence.

type SerializeTuple = SerializeTuple<'a>

Type returned from serialize_tuple for serializing the content of the tuple.

type SerializeTupleStruct = SerializeTupleStruct<'a>

Type returned from serialize_tuple_struct for serializing the content of the tuple struct.

type SerializeTupleVariant = SerializeTupleVariant<'a>

Type returned from serialize_tuple_variant for serializing the content of the tuple variant.

type SerializeMap = SerializeMap<'a>

Type returned from serialize_map for serializing the content of the map.

type SerializeStruct = SerializeStruct<'a>

Type returned from serialize_struct for serializing the content of the struct.

type SerializeStructVariant = SerializeStructVariant<'a>

Type returned from serialize_struct_variant for serializing the content of the struct variant.

fn serialize_unit(self) -> Result<()>
