AddTypes is the helper to add types definition to the schema.

Deprecated: use MustLoadQueryWithRules instead.

ReplaceRule replaces an existing rule from the rule set if one of the same name exists. If no match is found, it will add a new rule to the rule set.

TestAddRuleDuplicate confirms that calling AddRule twice with the same name does not create duplicate entries.

TestGetInnerNilSafety guarantees that GetInner is safe on a nil receiver and on an empty Rules struct, returning sensible defaults without panicking.

TestGetInnerReturnsCopy confirms that GetInner returns a copy of the internal map.

TestNewDefaultRules asserts that NewDefaultRules returns a non-empty rule set.

TestNewRules ensures that NewRules registers the provided Rules in the internal map and keeps ruleNameKeys in the expected order.

TestRemoveRule verifies that RemoveRule deletes the entry from both the internal map and ruleNameKeys slice.

TestReplaceRule checks that ReplaceRule actually swaps out the RuleFunc for an existing rule.
