Class: RuboCop::Cop::Style::RescueModifier

Checks for uses of ‘rescue` in its modifier form is added for following reasons:

• The syntax of modifier form ‘rescue` can be misleading because it might lead us to believe that `rescue` handles the given exception but it actually rescue all exceptions to return the given rescue block. In this case, value returned by handle_error or SomeException.
• Modifier form ‘rescue` would rescue all the exceptions. It would silently skip all exception or errors and handle the error. Example: If `NoMethodError` is raised, modifier form rescue would handle the exception.

Examples:

# bad some_method rescue handle_error # bad some_method rescue SomeException # good begin some_method rescue handle_error end # good begin some_method rescue SomeException handle_error end
