Variables

var PanicHandlers = []func(interface{}){logPanic}

PanicHandlers is a list of functions which will be invoked when a panic happens.

Functions

func FormatStack

func FormatStack() ([]byte, error)

func GetCallStackTrace

func GetCallStackTrace() string

func GetCaller

func GetCaller() string

func GetCallerWithSkip

func GetCallerWithSkip(skip int) string

GetCaller returns the caller of the function that calls it. The argument skip is the number of stack frames to skip before recording in pc, with 0 identifying the frame for Callers itself and 1 identifying the caller of Callers

func GetMetadata

func GetMetadata(ctx context.Context, key string) []string

func GetShortCaller

func GetShortCaller() string

func GoroutineID

func GoroutineID() uint64

low performance

func Must

func Must(err error)

Must panics on non-nil errors. Useful to handling programmer level errors

func NameOfFunction

func NameOfFunction(f interface{}) string

func Recover

func Recover()

must use defer Recover() not effective for calling defer func() {Recover()}()

func RecoverFromPanic

func RecoverFromPanic(err *error)

RecoverFromPanic replaces the specified error with an error containing the original error, and the call tree when a panic occurs. This enables error handlers to handle errors and panics the same way.
