safe

func Go ¶

func Go(name string, fn func(), onPanic func(recovered any))

Go runs fn in a new goroutine with panic recovery (see Run).

func Recover ¶

func Recover(name string)

Recover recovers and logs a panic (with stack). Defer it at the top of a goroutine whose body has its own cleanup defers (e.g. a channel close):

go func() {
	defer close(outChan)     // still runs after the panic is recovered
	defer safe.Recover("x")  // recovers so the process survives
	...
}()

func Run ¶

func Run(name string, fn func(), onPanic func(recovered any))

Run executes fn with panic recovery. On panic it logs the value and stack, then calls onPanic (if non-nil) with the recovered value so the caller can signal downstream (e.g. send an error chunk before a deferred close). Use this inside an existing goroutine body.
