Functions

func As

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

As is a utility function to call std error lib `As` function. As finds the first error in err's chain that matches target, and if so, sets target to that error value and returns true. Otherwise, it returns false. The chain consists of err itself followed by the sequence of errors obtained by repeatedly calling Unwrap.
