Trait serde::ser::SerializeTupleStruct [−][src]
pub trait SerializeTupleStruct { type Ok; type Error: Error; fn serialize_field<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_struct
.
Example use
use serde::ser::{Serialize, SerializeTupleStruct, Serializer}; struct Rgb(u8, u8, u8); impl Serialize for Rgb { fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where S: Serializer, { let mut ts = serializer.serialize_tuple_struct("Rgb", 3)?; ts.serialize_field(&self.0)?; ts.serialize_field(&self.1)?; ts.serialize_field(&self.2)?; ts.end() } }
Example implementation
The example data format presented on the website demonstrates an
implementation of SerializeTupleStruct
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, value: &T) -> Result<(), Self::Error> where
T: Serialize,
T: Serialize,
Serialize a tuple struct field.
fn end(self) -> Result<Self::Ok, Self::Error>
Finish serializing a tuple struct.
Implementors
