Struct Field

pub struct Field<Name: MoveType, Value: MoveType> {
    pub id: UID,
    pub name: Name,
    pub value: Value,
}

Internal object used for storing the field and value

Fields

id: UID

Determined by the hash of the object ID, the field name value and it’s type, i.e. hash(parent.id || name || Name)

name: Name

The value for the name of this field

value: Value

The value bound to this field
