# [−] [src] Trait num_traits::RefNum

    pub trait RefNum<Base>: NumOps<Base, Base> + for<'r> 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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
