Underlying returns all the underlying errors by iteratively checking if the error has an Underlying error. If e is nil, the returned slice will be nil.

func Wrap

func Wrap(err error) error

func WrapSkip

func WrapSkip(err error, skip int) error

WrapSkip the error and add the current Stack. The argument skip is the number of stack frames to ascend, with 0 identifying the caller of Wrap. If the error to be wrapped has a MultiStack, the current stack will be added to it. If the error to be wrapped is nil, a nil error is returned.


type Error

type Error struct {
	// contains filtered or unexported fields

Error provides the wrapper that adds multiple Stacks to an error. Each Stack represents a location in code thru which this error was wrapped.
