Trait burn::serde::ser::SerializeSeq

pub trait SerializeSeq {
    type Ok;
    type Error: Error;

    // Required methods
    fn serialize_element<T>(&mut self, value: &T) -> Result<(), Self::Error>
       where T: Serialize + ?Sized;
    fn end(self) -> Result<Self::Ok, Self::Error>;
}

Returned from Serializer::serialize_seq.

Example use

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

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

Example implementation

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

Required Associated Types

type Ok

Must match the Ok type of our Serializer.

type Error: Error

Must match the Error type of our Serializer.

Required Methods

fn serialize_element<T>(&mut self, value: &T) -> Result<(), Self::Error>

where T: Serialize + ?Sized,

Serialize a sequence element.

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

Finish serializing a sequence.

Object Safety

This trait is not object safe.
