Functions

func Do

func Do(attempt uint, sleep time.Duration, fn interface{}, args ...interface{}) ([]interface{}, error)

Do tries to execute the function by its value, function can take variadic arguments and return multiple return. You must put error as the last return value so that DoFunc can take decision that the call failed or not

func DoFunc

func DoFunc(attempts uint, sleep time.Duration, fn func(left uint) error) error

DoFunc tries to execute the function, it expects that the function will return an error

func UnaryInterceptor

func UnaryInterceptor(logger *zap.Logger, attempts uint, sleep time.Duration) grpc.UnaryClientInterceptor

UnaryInterceptor is the custom retry unary interceptor
