func(10, -10) # ✅ Correct
func(-10, 10) # ❌ Wrong -10 is not positive and 10 is not negative
func(0, -10) # ❌ Wrong 0 is not positive| MustBePositive | Validate that argument value is positive |
| MustBeNonPositive | Validate that argument value is non-positive |
| MustBeNegative | Validate that argument value is negative |
| MustBeNonNegative | Validate that argument value is non-negative |
| MustBeEqual | Validate that argument value is equal to another value |
| MustBeNotEqual | Validate that argument value is not equal to another value |
| MustBeGreaterThan | Validate that argument value is greater than another value |
| MustBeGreaterThanOrEqual | Validate that argument value is greater than or equal to another value |
| MustBeLessThan | Validate that argument value is less than another value |
| MustBeLessThanOrEqual | Validate that argument value is less than or equal to another value |
| MustBeIn | Validate that argument value is in a collection |
| MustBeBetween | Validate that argument value is between two other values |
| MustBeEmpty | Validate that a collection is empty |
| MustBeNonEmpty | Validate that a collection is non-empty |
| MustHaveLengthEqual | Validate that a collection has a specific length |
| MustHaveLengthGreaterThan | Validate that a collection has length greater than a specific value |
| MustHaveValuesBetween | Validate that all values in a collection are between two other values |
