Struct QsSerializer

pub struct QsSerializer<'a, W: 'a + Write> { /* private fields */ }

A serializer for the querystring format.

• Supported top-level inputs are structs and maps.

• Supported values are currently most primitive types, structs, maps and sequences. Sequences are serialized with an incrementing key index.

• Newtype structs defer to their inner values.

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.
