Struct Serializer

pub struct Serializer<'input, 'output, Target: UrlEncodedTarget> { /* private fields */ }

A serializer for the application/x-www-form-urlencoded format.

• Supported top-level inputs are structs, maps and sequences of pairs, with or without a given length.

• Supported keys and values are integers, bytes (if convertible to strings), unit structs and unit variants.

• Newtype structs defer to their inner values.

Implementations

impl<'input, 'output, Target: 'output + UrlEncodedTarget> Serializer<'input, 'output, Target>

pub fn new( urlencoder: &'output mut UrlEncodedSerializer<'input, Target>, ) -> Self

type Ok = &'output mut Serializer<'input, Target>

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.
