Enum rant::RantVar

pub enum RantVar {
    ByVal(RantValue),
    ByRef(Rc<RefCell<RantValue>>),
}

Represents a Rant variable of one of two flavors: by-value or by-reference.

Cloning

The Clone implementation for this type does not copy any data in ByRef variants; it only copies the reference. If you want to make a copy of the data in a Local regardless of its variant, use the .cloned() method.

Variants

ByVal(RantValue)

ByRef(Rc<RefCell<RantValue>>)
