| Overview |  |
Behaviours: hank_rule.
The rule emits a warning for each function argument that is consistently ignored in all function clauses.
To avoid this warning, remove the unused argument(s).
Note: This rule will not emit a warning if the function implements a behaviour callback or a NIF call.

ignored(Pattern::hank_rule:ignore_pattern(), FuncName::term()) -> boolean()
Rule ignore specifications. Example:
-hank([{unnecessary_function_arguments,
%% You can give a list of multiple specs or a single one
[%% Will ignore any unused argument from ignore_me/2 within the module
{ignore_me, 2},
%% Will ignore the 2nd argument from ignore_me_too/3 within the module
{ignore_me_too, 3, 2},
%% Will ignore any unused argument from any ignore_me_again/x
%% within the module (no matter the function arity)
ignore_me_again]}]).
