Returned from Serializer::serialize_struct.

Example use

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

struct Rgb {
    r: u8,
    g: u8,
    b: u8,
}

impl Serialize for Rgb {
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
    where
        S: Serializer,
    {
        let mut rgb = serializer.serialize_struct("Rgb", 3)?;
        rgb.serialize_field("r", &self.r)?;
        rgb.serialize_field("g", &self.g)?;
        rgb.serialize_field("b", &self.b)?;
        rgb.end()
    }
}

Example implementation

The example data format presented on the website demonstrates an implementation of SerializeStruct 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_field<T>( &mut self, key: &'static str, value: &T ) -> Result<(), Self::Error>

where T: Serialize + ?Sized,

Serialize a struct field.

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

Finish serializing a struct.

Provided Methods

fn skip_field(&mut self, key: &'static str) -> Result<(), Self::Error>

Indicate that a struct field has been skipped.

The default implementation does nothing.

Object Safety

This trait is not object safe.
