Functions

func As

func As(err error, target interface{}) bool

As finds the first error in err's chain that matches target, and if so, sets target to that error value and returns true.

The chain consists of err itself followed by the sequence of errors obtained by repeatedly calling Unwrap.

An error matches target if the error's concrete value is assignable to the value pointed to by target, or if the error has a method As(interface{}) bool such that As(target) returns true. In the latter case, the As method is responsible for setting target.

As will panic if target is not a non-nil pointer to either a type that implements error, or to any interface type. As returns false if err is nil.

func Code

func Code(err error) int

Code returns the http code for a error. It supports wrapped errors.

func Errorf

func Errorf(code int, reason, format string, a ...interface{}) error

Errorf returns an error object for the code, message and error info.

func Is

func Is(err, target error) bool

Is reports whether any error in err's chain matches target.

The chain consists of err itself followed by the sequence of errors obtained by repeatedly calling Unwrap.

An error is considered to match a target if it is equal to that target or if it implements a method Is(error) bool such that Is(target) returns true.

func IsBadRequest

func IsBadRequest(err error) bool

IsBadRequest determines if err is an error which indicates a BadRequest error. It supports wrapped errors.

func IsClientClosed

func IsClientClosed(err error) bool

IsClientClosed determines if err is an error which indicates a IsClientClosed error. It supports wrapped errors.

func IsConflict

func IsConflict(err error) bool

IsConflict determines if err is an error which indicates a Conflict error. It supports wrapped errors.

func IsForbidden

func IsForbidden(err error) bool

IsForbidden determines if err is an error which indicates a Forbidden error. It supports wrapped errors.

func IsGatewayTimeout

func IsGatewayTimeout(err error) bool

IsGatewayTimeout determines if err is an error which indicates a GatewayTimeout error. It supports wrapped errors.

func IsInternalServer

func IsInternalServer(err error) bool

IsInternalServer determines if err is an error which indicates an Internal error. It supports wrapped errors.

func IsNotFound

func IsNotFound(err error) bool

IsNotFound determines if err is an error which indicates an NotFound error. It supports wrapped errors.

func IsServiceUnavailable

func IsServiceUnavailable(err error) bool

IsServiceUnavailable determines if err is an error which indicates a Unavailable error. It supports wrapped errors.

func IsUnauthorized

func IsUnauthorized(err error) bool

IsUnauthorized determines if err is an error which indicates a Unauthorized error. It supports wrapped errors.

func Reason

func Reason(err error) string

Reason returns the reason for a particular error. It supports wrapped errors.

func Unwrap

func Unwrap(err error) error

Unwrap returns the result of calling the Unwrap method on err, if err's type contains an Unwrap method returning error. Otherwise, Unwrap returns nil.
