Functions

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 Error

type Error struct {
	// PackageType is the package type of the object emitting the error. For types, the value
	// matches that produced the the '%T' format specifier of the fmt package. For other elements,
	// such as functions, it is just the package name (e.g., "autorest").
	PackageType string

	// Method is the name of the method raising the error.
	Method string

	// Message is the error message.
	Message string
}

Error is the type that's returned when the validation of an APIs arguments constraints fails.

func NewError

func NewError(packageType string, method string, message string, args ...interface{}) Error

NewError creates a new Error object with the specified parameters. message is treated as a format string to which the optional args apply.

func (Error) Error

func (e Error) Error() string

Error returns a string containing the details of the validation failure.

type Validation

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

Validation stores parameter-wise validation.
