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) *containerDoesNotExistError

NewContainerDoesNotExistError returns a *containerDoesNotExistError referring to the given ID.

func NewContainerExistsError ¶

func NewContainerExistsError(id string) *containerExistsError

NewContainerExistsError returns a *containerExistsError 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) *processDoesNotExistError

NewProcessDoesNotExistError returns a *processDoesNotExistError 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.
