Operator Overloading
In Rust, many of the operators can be overloaded via traits. That is, some operators can
be used to accomplish different tasks based on their input arguments. This is possible
because operators are syntactic sugar for method calls. For example, the + operator in
a + b calls the add method (as in a.add(b)). This add method is part of the Add
trait. Hence, the + operator can be used by any implementor of the Add trait.
A list of the traits, such as Add, that overload operators can be found in core::ops.
