Expand description

拥有型且长度受限的通知；不实现输出消息内容的诊断格式化。

Implementations§

impl Notification

Source

pub fn new(fields: NotificationFields) -> Self

业务作用：在通知跨越异步队列前建立文本长度和控制字符边界。

参数说明：

  • fields：是仅在规则命中后构造的通知输入，不得包含凭据或绑定参数。

返回：标识最多 128 字符、方法最多 512 字符、SQL 最多 4096 字符的只读通知。

Source

pub fn fields(&self) -> &NotificationFields

业务作用：允许 transport 读取已经通过边界约束的消息。

参数说明：无。

返回：不可修改的通知内容，调用方不得写入普通日志。
