Struct serde_tagged::ser::internal::Serializer

pub struct Serializer<'a, S, T: ?Sized + 'a> { /* private fields */ }

A serializer that embeds a tag into to the provided value and then serializes it.

Due to the tag being embedded into the value, not all value-types are supported. The provided serializer performs the actual serialization and thus controls the data format. For more information on this trag-format and the supported values, see the module documentation.

Due to the tag being embedded into the value, not all value-types are supported. For more details see the module documentation.

Warning

This serializer does not provide any checks regarding collisions of the tag_key with field-names or map-keys. The responsibility for such checks reside with the caller.

Implementations

impl<'a, S, T> Serializer<'a, S, T>

where S: Serializer, T: Serialize + 'a + ?Sized,

pub fn new(delegate: S, tag_key: &'static str, tag: &'a T) -> Self

Creates a new Serializer with the specified tag-key, tag and underlying serializer.

Trait Implementations

impl<'a, S, T> HasDelegate for Serializer<'a, S, T>

where S: Serializer, T: Serialize + ?Sized,

type Ok = <S as Serializer>::Ok

type Error = <S as Serializer>::Error

type Delegate = S

fn delegate(self) -> S

Returns the delegate-serializer of this object.

impl<'a, S, T> Serializer for Serializer<'a, S, T>

where S: Serializer, T: Serialize + 'a + ?Sized,

type Ok = <S as Serializer>::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 = <S as Serializer>::Error

The error type when some error occurs during serialization.

type SerializeSeq = <S as Serializer>::SerializeSeq

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

type SerializeTuple = <S as Serializer>::SerializeTuple

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

type SerializeTupleStruct = <S as Serializer>::SerializeTupleStruct

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

type SerializeMap = <S as Serializer>::SerializeMap

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

type SerializeStruct = <S as Serializer>::SerializeStruct

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

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

type SerializeStructVariant = Impossible<<Serializer<'a, S, T> as Serializer>::Ok, <Serializer<'a, S, T> as Serializer>::Error>
