    type Amount: Copy + Display + Into<Amount>;

    // Required methods
    fn is_overflow_receive_msg(msg: &Map<String, Value>) -> bool;
    fn strip_middleware_msg(
        json_obj_memo: Map<String, Value>,
    ) -> Map<String, Value>;
    fn overflow_receiver(&self) -> &Self::AccountId;
    fn target_amount(&self) -> &Self::Amount;
}

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
