[][src]Trait serde::ser::SerializeTupleStruct

pub trait SerializeTupleStruct {
    type Ok;
    type Error: Error;
    fn serialize_field<T: ?Sized>(
        &mut self,
        value: &T

Returned from Serializer::serialize_tuple_struct.

Example use

This code runs with edition 2018
use serde::ser::{Serialize, SerializeTupleStruct, Serializer};

struct Rgb(u8, u8, u8);

impl Serialize for Rgb {
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
        S: Serializer,
        let mut ts = serializer.serialize_tuple_struct("Rgb", 3)?;

Example implementation

The example data format presented on the website demonstrates an implementation of SerializeTupleStruct for a basic JSON data format.

Associated Types

type Ok

Must match the Ok type of our Serializer.
