Functions

func Catch

func Catch(errRef *error)

func CatchFunc

func Errorf

func Errorf(format string, args ...any) error

func HandleNillable

func HandleNillable[T any](val *T, err error) (*T, error)

HandleNillable process cornor case of error handling. Patch fucking stupid lang design.

1. if err is not nil, return val & err
2. if val is nil, return nil & ErrNilValue
3. return val & nil

	// contains filtered or unexported fields
