Struct Attr 

pub struct Attr {
    pub cmd: Arc<dyn AttrCommand + Sync + Send>,
    pub is_public: bool,
    pub is_optional: bool,
    pub is_array: bool,
}

Attr holds the generation command used to generate an attribute in an entity.

AttrCommand provides the command pattern interface to apply and revert the attribute logic, supporting rolling, re-rolling, and unrolling entities.

Attr is cloneable so it can be shared throughout the class hierarchy. (See the method expand in ClassBuilder). The cmd inside Attr is using std::rc::Rc for that purpose.
