Functions

func NewErrorWithValidationError

func NewErrorWithValidationError(err error, packageType, method string) error

NewErrorWithValidationError appends package type and method name in validation error.

func Validate

func Validate(m []Validation) error

Validate method validates constraints on parameter passed in validation array.

Types

type Constraint

type Constraint struct {

	// Target field name for validation.
	Target string

	// Constraint name e.g. minLength, MaxLength, Pattern, etc.
	Name string

	// Rule for constraint e.g. greater than 10, less than 5 etc.
	Rule interface{}

	// Chain Validations for struct type
	Chain []Constraint
}

Constraint stores constraint name, target field name Rule and chain validations.

type Validation

type Validation struct {
	TargetValue interface{}
	Constraints []Constraint
}

Validation stores parameter-wise validation.
