Derive Macro Deserialize 

#[derive(Deserialize)]
{
    // Attributes available to this derive:
    #[serde]
}

Available on crate feature derive only.

Derive macro that generates a custom impl serde::Deserialize<'de> for named structs.

Remarks

Unlike serde’s default derive, this macro produces a deserialize_in_place() method that only updates fields present in the deserializer’s map, leaving absent fields at their current values.
