Struct serde_cbor::ser::Serializer
[−]
[src]
pub struct Serializer<W: Write> { /* fields omitted */ }
A structure for serializing Rust values into CBOR.
Methods
impl<W: Write> Serializer<W>
[src]
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.

impl<'a, W: Write> Serializer for &'a mut Serializer<W>
[src]
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. Read more
type Error = Error
The error type when some error occurs during serialization.
