Documentation

Overview

Package errortype defines helper for inspect common error types generated in standard library, so you don't need to import tons of packages in your file for sentinel error and custom error type.

Functions

func GetFsError

func GetFsError(err error) (error, bool)

func GetNetError

func GetNetError(err error) (netErr net.Error, ok bool)

func GetRuntimeError

func GetRuntimeError(err error) (rErr runtime.Error, ok bool)

RuntimeError is triggered by invalid operation like divide by 0, index out of range in slice. When user call panic, which accepts an interface, most of them will just give a simple string and does not satisfies the runtime.Error interface

func IsAlreadyExists

func IsAlreadyExists(err error) bool

FIXME: this is copy and paste, but can't pass an interface directly

func IsFsError

func IsFsError(err error) bool

func IsNetError

func IsNetError(err error) bool

func IsNotFound

func IsNotFound(err error) bool

func IsNotImplemented

func IsNotImplemented(err error) bool

FIXME: this is copy and paste, but can't pass an interface directly

func IsRuntimeError

func IsRuntimeError(err error) bool

func NewAlreadyExists

func NewAlreadyExists(name string) error

func NewNotFound

func NewNotFound(lookingFor string) error

func NewNotImplemented

func NewNotImplemented(feature string) error

func ToHTTPStatus

func ToHTTPStatus(err error) int

ToHTTPStatus converts error to http code based on their type It is similar to docker's https://github.com/moby/moby/blob/master/errdefs/http_helpers.go TODO: only a few types are supported and the assertions are actually resource consuming due to using reflection

Types

type ErrAlreadyExists

type ErrAlreadyExists interface {
	IsErrAlreadyExists()
}

type ErrNotFound

type ErrNotFound interface {
	IsErrNotFound()
}

type ErrNotImplemented

type ErrNotImplemented interface {
	IsErrNotImplemented()
}
