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()
}
