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

pub trait SerializeTupleStruct {
    type Ok;
    type Error: Error;
    fn serialize_field<T: ?Sized>(
        &mut self,
        value: &T
    ) -> Result<(), Self::Error>
    where
        T: Serialize

Returned from Serializer::serialize_tuple_struct.

Example use

use serde::ser::{Serialize, Serializer, SerializeTupleStruct};

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

Must match the Ok type of our Serializer.

Must match the Error type of our Serializer.
