Functions

func BaseStackTrace

func BaseStackTrace(e error) errors.StackTrace

BaseStackTrace gets the earliest errors.StackTrace in the given error's cause stack. This will be the stack trace which reaches closest to the error's actual origin. It returns nil if no stack trace is found in the cause stack.

func NewContainerDoesNotExistError

func NewContainerDoesNotExistError(id string) error

NewContainerDoesNotExistError returns an error referring to the given ID.

func NewContainerExistsError

func NewContainerExistsError(id string) error

NewContainerExistsError returns an error referring to the given ID.

func NewHresultError

func NewHresultError(hresult Hresult) error

NewHresultError produces a new error with the given HRESULT.

func NewProcessDoesNotExistError

func NewProcessDoesNotExistError(pid int) error

NewProcessDoesNotExistError returns an error referring to the given pid.

func WrapHresult

func WrapHresult(e error, hresult Hresult) error

WrapHresult produces a new error with the given HRESULT and wrapping the given error.

Types

type Hresult

type Hresult int32

Hresult is a type corresponding to the HRESULT error type used on Windows.

func GetHresult

func GetHresult(e error) (Hresult, error)

GetHresult interates through the error's cause stack (similiarly to how the Cause function in github.com/pkg/errors operates). At the first error it encounters which implements the Hresult() method, it return's that error's HRESULT. This allows errors higher up in the cause stack to shadow the HRESULTs of errors lower down.

type StackTracer

type StackTracer interface {
	StackTrace() errors.StackTrace
}

StackTracer is an interface originating (but not exported) from the github.com/pkg/errors package. It defines something which can return a stack trace.
