Expand description

命令总线（Command Bus）

  • 负责根据命令的具体类型路由到对应的处理器；
  • 框架可提供不同实现（如进程内、消息队列等）；
  • 该 trait 带有泛型方法，通常以具体实现类型注入使用。

Required Methods§

Source

fn dispatch<'life0, 'life1, 'async_trait, C, R>( &'life0 self, ctx: &'life1 AppContext, cmd: C, ) -> Pin<Box<dyn Future<Output = Result<R, AppError>> + Send + 'async_trait>>
where C: Send + 'static + 'async_trait, R: Send + 'static + 'async_trait, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

分发命令到对应处理器

  • ctx：应用上下文（链路追踪、幂等键等）
  • cmd：具体命令实例
  • 返回：命令处理结果

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
