TODO: Remove or replace most of these errors.

Some of the errors should be replaced with package specific errors and others should be removed entirely.

Functions

func ToLinux

func ToLinux(err *Error) *linux.Errno

ToLinux translates an Error to a corresponding *linux.Errno value.

Types

type Error

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

Error represents an internal error.

func FromError

func FromError(err error) *Error

FromError converts a generic error to an *Error.

TODO: Remove this function.

func FromHost

func FromHost(err syscall.Errno) *Error

FromHost translates a syscall.Errno to a corresponding Error value.

func New

func New(message string, linuxTranslation *linux.Errno) *Error

New creates a new Error and adds a translation for it.

func NewWithoutTranslation

func NewWithoutTranslation(message string) *Error

NewWithoutTranslation creates a new Error. If translation is attempted on the error, translation will fail.

func TranslateNetstackError

func TranslateNetstackError(err *tcpip.Error) *Error

TranslateNetstackError converts an error from the tcpip package to a sentry internal error.

func (*Error) String

func (e *Error) String() string

String implements fmt.Stringer.String.

func (*Error) ToError

func (e *Error) ToError() error

ToError translates an Error to a corresponding error value.

TODO: Remove this.
