Types

type Error

type Error struct {
	Err  error
	Type ErrorType
	Meta interface{}
}

func New

func New(err error, t ErrorType, meta interface{}) *Error

func NewPrivate

func NewPrivate(err string) *Error

func NewPrivatef

func NewPrivatef(format string, v ...interface{}) *Error

func NewPublic

func NewPublic(err string) *Error

shortcut for creating a public *Error from string

func NewPublicf

func NewPublicf(format string, v ...interface{}) *Error

func Newf

func Newf(t ErrorType, meta interface{}, format string, v ...interface{}) *Error

func (*Error) Error

func (msg *Error) Error() string

AbortWithMsg implements the error interface.

func (*Error) IsType

func (msg *Error) IsType(flags ErrorType) bool

IsType judges one error.

func (*Error) JSON

func (msg *Error) JSON() interface{}

JSON creates a properly formatted JSON

func (*Error) SetMeta

func (msg *Error) SetMeta(data interface{}) *Error

SetMeta sets the error's meta data.

func (*Error) SetType

func (msg *Error) SetType(flags ErrorType) *Error

SetType sets the error's type.

func (*Error) Unwrap

func (msg *Error) Unwrap() error

type ErrorChain

type ErrorChain []*Error

func (ErrorChain) ByType

func (a ErrorChain) ByType(typ ErrorType) ErrorChain

ByType returns a readonly copy filtered the byte. ie ByType(hertz.ErrorTypePublic) returns a slice of errors with type=ErrorTypePublic.

func (ErrorChain) Errors

func (a ErrorChain) Errors() []string

Errors returns an array will all the error messages. Example:

c.Error(errors.New("first"))
c.Error(errors.New("second"))
c.Error(errors.New("third"))
c.Errors.Errors() // == []string{"first", "second", "third"}

func (ErrorChain) JSON

func (a ErrorChain) JSON() interface{}

func (ErrorChain) Last

func (a ErrorChain) Last() *Error

Last returns the last error in the slice. It returns nil if the array is empty. Shortcut for errors[len(errors)-1].

func (ErrorChain) String

func (a ErrorChain) String() string

type ErrorType

type ErrorType uint64

ErrorType is an unsigned 64-bit error code as defined in the hertz spec.

const (
	// ErrorTypeBind is used when Context.Bind() fails.
	ErrorTypeBind ErrorType = 1 << iota
	// ErrorTypeRender is used when Context.Render() fails.
	ErrorTypeRender
	// ErrorTypePrivate indicates a private error.
	ErrorTypePrivate
	// ErrorTypePublic indicates a public error.
	ErrorTypePublic
	// ErrorTypeAny indicates any other error.
	ErrorTypeAny
)
