Crate serde_default 

Generate a Default impl based on field-level defaults in serde attributes.

Usage

On a struct that derives Serialize or Deserialize, add DefaultFromSerde.

#[derive(Debug, DefaultFromSerde, PartialEq, Eq)]
pub struct MyStruct {
    #[serde(default = "field_1_default")]
    field1: u16,
    #[serde(default)]
    field2: String,
}

fn field_1_default() -> u16 {
    3
}

fn main() {
    assert_eq!(MyStruct::default(), MyStruct { field1: 3, field2: "".into() });
}
