ⓘThis code runs with edition 2018
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.
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: ?Sized>(
&mut self,
key: &'static str,
value: &T
) -> Result<(), Self::Error> where
T: Serialize,
&mut self,
key: &'static str,
value: &T
) -> Result<(), Self::Error> where
T: Serialize,
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.
