Functions

func Between

func Between[T Number](lowerBound, upperBound T) func(T) error

Between validates if a value is within the specified lower and upper bounds (inclusive).

func LengthBetween

func LengthBetween(lowerBound, upperBound int) func(string) error

LengthBetween validates if a string's length is between the specified bounds (inclusive).

func LengthMax

func LengthMax(upperBound int) func(string) error

LengthMax ensures a string's length does not exceed the specified upperBound.

func LengthMin

func LengthMin(lowerBound int) func(string) error

LengthMin ensures a string's length is at least the specified lowerBound.

func Max

func Max[T Number](upperBound T) func(T) error

Max validates if a value is less than or equal to the specified upper bound.

func Min

func Min[T Number](lowerBound T) func(T) error

Min validates if a value is greater than or equal to the specified lower bound.

func MultipleOf

func MultipleOf[T Integer](divisor T) func(T) error

MultipleOf validates if a value is a multiple of the specified divisor.

func Negative

func Negative[T Number](value T) error

Negative checks if the given numeric value is negative.

func NonNegative

func NonNegative[T Number](value T) error

NonNegative validates that the provided numeric value is non-negative (including zero).

func NotEmpty

func NotEmpty(value string) error

func Positive

func Positive[T Number](value T) error

Positive checks if the provided value is positive (excluding zero).
