Serde supports this kind of fine-tuning of the serialization and deserialization using attributes. I think this does what you want:
#[derive(Serialize, Deserialize)]
struct Point {
x: f64,
y: f64,
#[serde(skip_serializing_if = "Vec::is_empty", default)]
children: Vec<u8>,
}
- The
skip_serializing_if
attribute specifies a function that is called to decide whether to serialize the current value of the field. - The
default
attribute says to use theDefault::default()
value of the field if it is not present in the input.

Oh, I did not know that.
Thank you so much.
