Struct pythnet_sdk::wire::Serializer

pub struct Serializer<W: Write, B: ByteOrder> { /* private fields */ }

A type for Pyth’s common serialization format. Note that a ByteOrder type param is required as we serialize in both big and little endian depending on different use-cases.

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

fn serialize_seq( self, len: Option<usize> ) -> Result<Self::SerializeSeq, Self::Error>

We use the fact that len can be None here to optionally not prefix a sequence when we serialize. This allows us to disable length prefixing optionally when writing serializers by hand. See PrefixlessVec for an example.

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 = SerializerError

The error type when some error occurs during serialization.
