'errors.As' can be replaced with 'errors.AsType'

Reports calls to errors.As that can be replaced with errors.AsType.

In Go 1.26 and later, errors.AsType[T] returns the matched error value directly. This removes the separately declared variable and the pointer passed to errors.As.

Example:

func Describe(err error) string { var pe *PathError if errors.As(err, &pe) { return fmt.Sprintf("path error during %s", pe.Op) } return "other" }

To fix the code, use the Replace errors.As with AsType[*PathError] quick-fix.

After the quick-fix is applied:

func Describe(err error) string { if pe, ok := errors.AsType[*PathError](err); ok { return fmt.Sprintf("path error during %s", pe.Op) } return "other" }
