type Error
type Error string
Error represents a constant error string
func (Error) Error
func (e Error) Error() string

type Trace
type Trace struct {
Traces []Call
}
Trace represents the call stack for an error
func (Trace) Trace

Trace returns a byte slice containing a description of the call stack
func (Trace) Unwrap
func (t Trace) Unwrap() error

type Wrapper
type Wrapper interface {
Unwrap() error
}
