class RuboCop::Cop::Style::SafeNavigationChainLength

Enforces safe navigation chains length to not exceed the configured maximum. The longer the chain is, the harder it becomes to track what on it could be returning ‘nil`.

There is a potential interplay with ‘Style/SafeNavigation` - if both are enabled and their settings are “incompatible”, one of the cops will complain about what the other proposes.

E.g. if ‘Style/SafeNavigation` is configured with `MaxChainLength: 2` (default) and this cop is configured with `Max: 1`, then for `foo.bar.baz if foo` the former will suggest `foo&.bar&.baz`, which is an offense for the latter.

@example Max: 2 (default)
