系统消息处理器 trait

Provided Methods

fn process<'life0, 'life1, 'async_trait>( &'life0 self, system_message: &'life1 MessageBody, ) -> Pin<Box<dyn Future<Output = (u16, String)> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

处理系统消息，返回 (状态码, 响应消息)

fn pre_start(&self)

启动前的初始化

fn raw_process<'life0, 'life1, 'async_trait>( &'life0 self, system_message: &'life1 MessageBody, ) -> Pin<Box<dyn Future<Output = AckMessage> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,
