Unused assignment detected RB-LI1078
Bug risk
Minor
Autofix Unused assignments are unnecessary and can be removed. In case the declaration is intentional, you can prefix _ before the variable name.
This issue is autofixable, and the behavior of the autofix is tweakable by using the FixType switch, which accepts either of Replace or Remove. The default is to remove the unused assignment.
