pub trait RefNum<Base>: NumOps<Base, Base> + for<'r> NumOps<&'r Base, Base> { }Expand description
The trait for Num references which implement numeric operations, taking the
second operand either by value or by reference.
This is automatically implemented for all types which implement the operators. It covers
every type implementing the operations though, regardless of it being a reference or
related to Num.
