Struct Serializer 

pub struct Serializer;

A serde::Serializer whose output is a CanonicalJsonValue.

This behaves similarly to serde_json::value::Serializer, except for the following restrictions which return errors:

• Integers must be in the range accepted by js_int::Int.
• Floats and bytes are not serializable.
• Booleans and integers cannot be used as keys for an object. serde_json accepts those types as keys by serializing them as strings.
• The same key cannot be serialized twice in an object. serde_json uses the last value that is serialized for the same key (at the time of writing).

Trait Implementations

impl Serializer for Serializer

type Ok = CanonicalJsonValue

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 = CanonicalJsonError

The error type when some error occurs during serialization.

type SerializeSeq = SerializeArray

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

type SerializeTuple = SerializeArray

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

type SerializeTupleStruct = SerializeArray

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

type SerializeTupleVariant = SerializeNamedValue<SerializeArray>

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

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

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