[][src]Trait serde::ser::SerializeSeq

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

Returned from Serializer::serialize_seq.

Example use

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

impl<T> Serialize for Vec<T>
    T: Serialize,
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
        S: Serializer,
        let mut seq = serializer.serialize_seq(Some(self.len()))?;
        for element in self {

Example implementation

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

Associated Types

type Ok

Must match the Ok type of our Serializer.
