interface Multiply

interface Multiply<'Rhs, 'Out> {
    fn multiply(lhs: self, rhs: 'Rhs): 'Out
}

Protocol for the * operator.

Multiply.multiply(lhs, rhs) returns the result of lhs * rhs. The left-hand type is the implementor (self); the interface type parameters describe the right-hand operand and the output type. That lets an impl choose a result that is not necessarily the same type as the left-hand operand.

pub type Quantity Int
pub type Scale Int

impl Multiply<Scale, Quantity> for Quantity {
  fn multiply(lhs: Quantity, rhs: Scale): Quantity { ... }
}
