+
+## 规则
+
+每个 `Matcher` 拥有一个 `Rule` ，其中是 `RuleChecker` 的集合，只有当所有 `RuleChecker` 检查结果为 `True` 时继续运行。
+
+:::tip 提示
+`RuleChecker` 既可以是 async function 也可以是 sync function
+:::
+
+
+## _class_ `Rule`
+
+基类：`object`
+
+
+* **说明**
+
+    `Matcher` 规则类，当事件传递时，在 `Matcher` 运行前进行检查。
+
+
+
+* **示例**
+
+
+```python
+Rule(async_function) & sync_function
+# 等价于
+from nonebot.utils import run_sync
+Rule(async_function, run_sync(sync_function))
+```
+
+
+### `__init__(*checkers)`
+
+
+* **参数**
+
+    
+    * `*checkers: Callable[[Bot, Event, dict], Awaitable[bool]]`: **异步** RuleChecker
+
+
+
+### `checkers`
+
+
+* **说明**
+
+    存储 `RuleChecker`
+
+
+
+* **类型**
+
+    
+    * `Set[Callable[[Bot, Event, dict], Awaitable[bool]]]`
+
+
+
+### _async_ `__call__(bot, event, state)`
+
+
+* **说明**
+
+    检查是否符合所有规则
+
+
+
+* **参数**
+
+    
+    * `bot: Bot`: Bot 对象
+
+
+    * `event: Event`: Event 对象
+
+
+    * `state: dict`: 当前 State
+
+
+
+* **返回**

-### `default(o)`
-
-Implement this method in a subclass such that it returns
-a serializable object for `o`, or calls the base implementation
-(to raise a `TypeError`).
-
-For example, to support arbitrary iterators, you could
-implement default like this:
-
-```default
-def default(self, o):
-    try:
-        iterable = iter(o)
-    except TypeError:
-        pass
-    else:
-        return list(iterable)
-    # Let the base class default method raise the TypeError
-    return JSONEncoder.default(self, o)
-```
