Functions

func As

func As(err error, target interface{}) bool

func Base

func Base(format string, a ...interface{}) error

Base returns a simple error with no stack trace attached

func Err

func Err(e interface{}, fmtParams ...interface{}) error

Err returns an error with stack trace

func FullTrace

func FullTrace(err error) string

FullTrace returns the error type, message, and stack trace

func HasTrace

func HasTrace(err error) bool

HasTrace checks if error has a trace attached

func Is

func Is(err, target error) bool

Is, As, and Unwrap call through to the builtin errors functions with the same name

func Prefix

func Prefix(prefix string, err interface{}) error

Prefix prefixes the message of the error with the given string

func Trace

func Trace(err error) string

Trace returns the stack trace
