Struct Serializer

pub struct Serializer<W, O>
where
    O: Options,
{ /* private fields */ }

An Serializer that encodes values directly into a Writer.

The specified byte-order will impact the endianness that is used during the encoding.

This struct should not be used often. For most cases, prefer the encode_into function.

Implementations

impl<W, O> Serializer<W, O>

where W: Write, O: Options,

pub fn new(w: W, options: O) -> Serializer<W, O>

Creates a new Serializer with the given Writer.

Trait Implementations

impl<'a, W, O> Serializer for &'a mut Serializer<W, O>

where W: Write, O: Options,

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 = Box<ErrorKind>

The error type when some error occurs during serialization.

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

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

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