Struct Serializer

pub struct Serializer;

Create a serde::Serializer that serializes a Serializee into a Value.

Trait Implementations

impl Default for Serializer

fn default() -> Serializer

Returns the “default value” for a type.

impl Serializer for Serializer

type Ok = Value

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 = SerializeVec

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

type SerializeTuple = SerializeVec

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

type SerializeTupleStruct = SerializeVec

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

type SerializeTupleVariant = SerializeTupleVariant

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

type SerializeMap = SerializeMap

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

type SerializeStruct = SerializeMap

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

type SerializeStructVariant = SerializeStructVariant

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