This addresses Issue #2268 .
It lints for implementations of arithmetic operations and
OpAssignimplementations.Currently it only lints for the arithmetic operations
Add,Sub,Mul,Div. Other traits of binary operations can be easily added though.Regarding the
OpAssignimplementations, it lints for every possibleOpAssigntrait. If you implementOpAssign, you probably have implementedOpalready, so that the implementation is a one-liner.If there are multiple binary operations in an expression (e.g.
(a + b) % 10), it will not lint.
