# NoneBot.rule 模块
|
||
|
||
## 规则
|
||
|
||
每个事件响应器 `Matcher` 拥有一个匹配规则 `Rule` ，其中是 **异步** `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，但在最终会被 `nonebot.utils.run_sync` 转换为 async function
|
||

|
||
|
||
|
||
## _class_ `Rule`
