Creates a new JSON serializer.

impl<'a, W> Serializer<W, PrettyFormatter<'a>> where W: Write

fn pretty(writer: W) -> Self

Creates a new JSON pretty print serializer.

impl<W, F> Serializer<W, F> where W: Write, F: Formatter

Trait Implementations

impl<'a, W, F> Serializer for &'a mut Serializer<W, F> where W: Write,
        F: Formatter

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 = Compound<'a, W, F>

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

type SerializeTuple = Compound<'a, W, F>

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

type SerializeTupleStruct = Compound<'a, W, F>

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

type SerializeTupleVariant = Compound<'a, W, F>

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

type SerializeMap = Compound<'a, W, F>

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

type SerializeStruct = Compound<'a, W, F>

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

type SerializeStructVariant = Compound<'a, W, F>

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