/// tip

Having the return model ensure that a value is always available and always `int` (not `None`) is very useful for the API clients, they can write much simpler code having this certainty.

### "컨텍스트 관리자"란 { #what-are-context-managers }

"컨텍스트 관리자"는 Python에서 `with` 문에서 사용할 수 있는 모든 객체를 의미합니다.

예를 들어, [with를 사용해 파일을 읽을 수 있습니다](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

내부적으로 `open("./somefile.txt")` 는 "컨텍스트 관리자(Context Manager)"라고 불리는 객체를 생성합니다.

	z.RootDisk, err = dc.ReadBool()
	if err != nil {
		err = msgp.WrapError(err, "RootDisk")
		return
	}
	z.Healing, err = dc.ReadBool()
	if err != nil {
		err = msgp.WrapError(err, "Healing")
		return
	}
	z.Scanning, err = dc.ReadBool()
	if err != nil {
		err = msgp.WrapError(err, "Scanning")
		return
	}
	z.Endpoint, err = dc.ReadString()

 *       does it offer a way to batch multiple events from a single producer together.
 *   <li>It doesn't support backpressure and other features needed for resilience.
 *   <li>It doesn't provide much control of threading.
 *   <li>It doesn't offer much monitoring.
 *   <li>It doesn't propagate exceptions, so apps don't have a way to react to them.
 *   <li>It doesn't interoperate well with RxJava, coroutines, and other more commonly used

Multiple files can be added. Files ending in '.zip' will be searched
for 'xl.meta' files. Wildcards are accepted: 'testdir/*.txt' will compress
all files in testdir ending with '.txt', directories can be wildcards
as well. 'testdir/*/*.txt' will match 'testdir/subdir/b.txt', double stars
