func Capture ¶

func Capture(rErr *error, fn func() error) func()

Capture is a wrapper function which can be used to capture errors from closing via a defer. An example:

func Example() (err error) {
    f, _ := os.Open(...)
    defer errors.Capture(&err, f.Close)()
    ...
    return

Doing this will result in the error from the f.Close() call being put in the error via a ptr, if the error is not nil
