§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.

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
