Trait RefNum
num::traits
pub trait RefNum<Base>: NumOps<Base, Base> + NumOps<&'r Base, Base> { }
The trait for references which implement numeric operations, taking the second operand either by value or by reference.
This is automatically implemented for types which implement the operators.
impl<T, Base> RefNum<Base> for T where T: NumOps<Base, Base> + NumOps<&'r Base, Base>,
