Macro assert_impl_commons 

macro_rules! assert_impl_commons {
    ($type:ty) => { ... };
}

Assert that a type implements all common traits. The common traits are Clone, Eq, PartialEq, Ord, PartialOrd, Debug, Display, Default, Send, Sync, Serialize, DeserializeOwned. (DeserializeOwned is used instead of Deserialize because of lifetime issues, and Deserialize<’static> auto-implements DeserializeOwned.)
