* @param newCount the desired count of the element in this multiset
   * @return {@code true} if the condition for modification was met. This implies that the multiset
   *     was indeed modified, unless {@code oldCount == newCount}.
   * @throws IllegalArgumentException if {@code oldCount} or {@code newCount} is negative

For example, a compiler must not discard <code>i</code> and reload it
a second time from <code>*p</code> in this program:
</p>

<pre>
i := *p
if i &lt; 0 || i &gt;= len(funcs) {
	panic("invalid function index")
}
... complex code ...
// compiler must NOT reload i = *p here
funcs[i]()
</pre>

<p>
If the complex code needs many registers, a compiler for single-threaded programs

Sie können auch die Kommandozeilenoption `--workers` verwenden, um einen asynchronen Multiprozess-Server zu erhalten.

* `Field(index=True)`는 SQLModel에 해당 열에 대해 **SQL 인덱스**를 생성하도록 지시합니다. 이를 통해 데이터베이스에서 이 열로 필터링된 데이터를 읽을 때 더 빠르게 조회할 수 있습니다.

    SQLModel은 `str`으로 선언된 항목이 SQL 데이터베이스에서 `TEXT` (또는 데이터베이스에 따라 `VARCHAR`) 유형의 열로 저장된다는 것을 인식합니다.

现在我们将使用一个简单的依赖项来读取一个自定义的 `X-Token` 请求首部：

{* ../../docs_src/bigger_applications/app_an_py310/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | 提示

我们正在使用虚构的请求首部来简化此示例。

但在实际情况下，使用集成的[安全性实用工具](security/index.md)会得到更好的效果。

## 其他使用 `APIRouter` 的模块 { #another-module-with-apirouter }

假设你在位于 `app/routers/items.py` 的模块中还有专门用于处理应用程序中「项目」的端点。

你具有以下*路径操作*：

* `/items/`
* `/items/{item_id}`

// [Reader.ReadBytes] or ReadString instead.
// ReadSlice returns err != nil if and only if line does not end in delim.
func (b *Reader) ReadSlice(delim byte) (line []byte, err error) {
	s := 0 // search start index
	for {
		// Search buffer.
		if i := bytes.IndexByte(b.buf[b.r+s:b.w], delim); i >= 0 {
			i += s
			line = b.buf[b.r : b.r+i+1]
			b.r += i + 1
			break
		}

		// Pending error?

			})
			t.Errorf("expected no active streams, got %d outgoing: %v", stats.OutgoingStreams, found)
		}
		return
	}
}

// Inserted manually.
func _() {
	// An "invalid array index" compiler error signifies that the constant values have changed.
	// Re-run the stringer command to generate them again.
