feat: Add KeysInValidator for validating fields containing specific keys

[bangadam]

References

Issue(s): #201
Discussion: None

Description

This validator ensures that all keys in the object under validation are part of the specified parameter slice. The main benefits of this addition are:

• It provides a simple and efficient way to validate that an object contains only the allowed keys, which enhances data integrity and consistency.
• It reduces the need for custom validation logic in individual projects, promoting code reusability and maintainability.

Possible drawbacks

• The KeysIn validator assumes that the object being validated is a map[string]interface{}. If the context value is not of this type, the validation will fail

You forgot to add the default language lines in lang/default.go.

It is correct and this is how it should be done. 👍🏻

Implementation looks correct to me. The third test case should expect true instead of false.

LGTM after these minor changes.

Can you move back the validator to a keysin.go file please? This doesn't belong to the string.go file since we are validating an object.
