🦋 ARGUMENTS 🦋

• rule — a pointer to a rule. literally just a pointer to a struct ima_rule_entry, the rule in question 👑
• func_data — the data to match against the measure rule data. this is the thing we're vibe-checking against the rule 🔥
• cred — a pointer to a credentials structure for user validation. yes she cares about who you are, main character energy fr 💜
