Constants

const DNS1123LabelMaxLength int = 63

DNS1123LabelMaxLength is a label's max length in DNS (RFC 1123).

const DNS1123SubdomainMaxLength int = 253

DNS1123SubdomainMaxLength is a subdomain's max length in DNS (RFC 1123).

const LabelValueMaxLength int = 63

LabelValueMaxLength is a label's max length.

Functions

func EmptyError

func EmptyError() string

EmptyError returns a string explanation of a "must not be empty" validation failure.

func InclusiveRangeError

func InclusiveRangeError(lo, hi int) string

InclusiveRangeError returns a string explanation of a numeric "must be between" validation failure.

func IsDNS1123Label

func IsDNS1123Label(value string) []string

IsDNS1123Label tests for a string that conforms to the definition of a label in DNS (RFC 1123).

func IsDNS1123Subdomain

func IsDNS1123Subdomain(value string) []string

IsDNS1123Subdomain tests for a string that conforms to the definition of a subdomain in DNS (RFC 1123).

func IsInRange

func IsInRange(value int, min int, max int) []string

IsInRange tests that the argument is in an inclusive range.

func IsQualifiedName

func IsQualifiedName(value string) []string

IsQualifiedName tests whether the value passed is what IAM calls a "qualified name". This is a format used in various places throughout the system. If the value is not valid, a list of error strings is returned. Otherwise an empty list (or nil) is returned.

func IsValidIP

func IsValidIP(value string) []string

IsValidIP tests that the argument is a valid IP address.

func IsValidIPv4Address

func IsValidIPv4Address(fldPath *field.Path, value string) field.ErrorList

IsValidIPv4Address tests that the argument is a valid IPv4 address.

func IsValidIPv6Address

func IsValidIPv6Address(fldPath *field.Path, value string) field.ErrorList

IsValidIPv6Address tests that the argument is a valid IPv6 address.

func IsValidLabelValue

func IsValidLabelValue(value string) []string

IsValidLabelValue tests whether the value passed is a valid label value. If the value is not valid, a list of error strings is returned. Otherwise an empty list (or nil) is returned.

func IsValidPassword

func IsValidPassword(password string) error

IsValidPassword validate password.

func IsValidPercent

func IsValidPercent(percent string) []string

IsValidPercent checks that string is in the form of a percentage.

func IsValidPortNum

func IsValidPortNum(port int) []string

IsValidPortNum tests that the argument is a valid, non-zero port number.

func MaxLenError

func MaxLenError(length int) string

MaxLenError returns a string explanation of a "string too long" validation failure.

func RegexError

func RegexError(msg string, fmt string, examples ...string) string

RegexError returns a string explanation of a regex validation failure.

Types

type Validator

type Validator struct {
	// contains filtered or unexported fields
}

Validator is a custom validator for configs.

func NewValidator

func NewValidator(data interface{}) *Validator

NewValidator creates a new Validator.

func (*Validator) Validate

func (v *Validator) Validate() field.ErrorList

Validate validates config for errors and returns an error (it can be casted to ValidationErrors, containing a list of errors inside). When error is printed as string, it will automatically contains the full list of validation errors.
