Validation library does not trim the data unlike CI3's. Generally, HTML encoding should be done in Views.
When using native functions, it needs one or three params. $rule($value) or $rule($value, $param, $data). It seems there is no function to fit the API. CI3's validation alters data. CI4 does not.

Description
The Validation library docs is misleading, especially in the context that CI 3 validation used to alter data.
