[−][src]Trait serde::ser::SerializeTuple

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

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

Returned from Serializer::serialize_tuple.

Example use

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

impl<A, B, C> Serialize for (A, B, C)
where
    A: Serialize,
    B: Serialize,
    C: Serialize,
{
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
    where
        S: Serializer,
    {
        let mut tup = serializer.serialize_tuple(3)?;
        tup.serialize_element(&self.0)?;
        tup.serialize_element(&self.1)?;
        tup.serialize_element(&self.2)?;
        tup.end()
    }
}
use serde::ser::{Serialize, Serializer, SerializeTuple};

impl<T> Serialize for [T; 16]
where
    T: Serialize,
{
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
    where
        S: Serializer,
    {
        let mut seq = serializer.serialize_tuple(16)?;
        for element in self {
            seq.serialize_element(element)?;
        }
        seq.end()
    }
}

Example implementation

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

Associated Types

Must match the Ok type of our Serializer.

Must match the Error type of our Serializer.

Required Methods

Serialize a tuple element.

Finish serializing a tuple.
