Struct AttrCommandUseEntity 

pub struct AttrCommandUseEntity {
    pub name: String,
    pub class_names: ClassNamesToRoll,
    pub min: CardinalityValue,
    pub max: CardinalityValue,
    /* private fields */
}

Use a collected entity by class name:

attribute ? ClassName

or

[1..3 attribute] ? ClassName

• The class name can be a concrete or a base class
• The used entity will be made unavailable for others until it gets recycled

Any selected entity can be ‘injected’ with new attributes or attribute overrides:

attribute ? ClassName {
    new_attribute = "some value"
}

Fields

name: String

class_names: ClassNamesToRoll

min: CardinalityValue

max: CardinalityValue
