Struct serde_cbor::ser::Serializer

pub struct Serializer<W: Write> { /* fields omitted */ }

A structure for serializing Rust values into CBOR.

Methods

impl<W: Write> Serializer<W>

fn new(writer: W) -> Serializer<W>

Creates a new CBOR serializer.

fn packed(writer: W) -> Serializer<W>

Creates a new packed CBOR serializer.

In packed mode all struct field names and enum variant names are not serialized instead the index position of the field is used.

fn self_describe(&mut self) -> Result<()>

Writes the CBOR self-describe tag to the stream.

Tagging allows a decoder to distinguish different file formats based on their content without other information.

type Error = Error

Must match the Error type of our Serializer.

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

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.
