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>
    where
        S: Serializer,
    {
        let mut ts = serializer.serialize_tuple_struct("Rgb", 3)?;
        ts.serialize_field(&self.0)?;
        ts.serialize_field(&self.1)?;
        ts.serialize_field(&self.2)?;
        ts.end()
    }
}

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.
