Function test_fuzz::deserialize_ref

pub fn deserialize_ref<'de, D, T>(
    deserializer: D
) -> Result<&'static T, D::Error> where
    D: Deserializer<'de>,
    T: DeserializeOwned + Debug, 

deserialize_ref functions similar to leak!, but it is meant to be used with Serde’s deserialize_with field attribute.
