Returned from Serializer::serialize_tuple_variant.

        let mut tv = serializer.serialize_tuple_variant("E", 0, "T", 2)?;

Required Associated Types

type Ok

Must match the Ok type of our Serializer.

type Error: Error

Must match the Error type of our Serializer.

Required Methods

fn serialize_field<T>(&mut self, value: &T) -> Result<(), Self::Error>

where T: Serialize + ?Sized,

Serialize a tuple variant field.

fn end(self) -> Result<Self::Ok, Self::Error>

Finish serializing a tuple variant.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<Ok, E> SerializeTupleVariant for Impossible<Ok, E>

where E: Error,

type Ok = Ok

type Error = E
