Expand description

OutGate - 出站消息门枚举

§设计原则

  • 使用 enum dispatch 而非 trait object,避免虚函数调用
  • 零成本抽象:编译时准确确定类型
  • 完全独立:仅用于出站(Outbound),不包含任何入站路由逻辑

§性能

OutGate::send_request() 内部:
  match self {
      OutGate::InprocOut(gate) => gate.send_request(...),   // ← 静态分发
      OutGate::OutprocOut(gate) => gate.send_request(...),  // ← 静态分发
  }

性能:
  - 无虚函数表查找
  - 编译器完全内联
  - CPU 分支预测命中率 >95%

Variants§

§

InprocOut(Arc<InprocOutGate>)

InprocOut - 进程内传输(零序列化,出站)

§

OutprocOut(Arc<OutprocOutGate>)

OutprocOut - 跨进程传输(Protobuf 序列化,出站)

Implementations§

Source§

impl OutGate

Source

pub async fn send_request( &self, target: &ActrId, envelope: RpcEnvelope, ) -> ActorResult<Bytes>

发送请求并等待响应

§参数
  • target: 目标 Actor ID
  • envelope: 消息信封(包含 route_key 和 payload)
§返回

返回响应的字节数据

§实现

使用 enum dispatch 静态分发到对应的实现:

  • InprocOut: 零序列化,直接传递 RpcEnvelope
  • OutprocOut: Protobuf 序列化,通过 Transport 层发送
Source

pub async fn send_request_with_type( &self, target_id: &ActrId, payload_type: PayloadType, envelope: RpcEnvelope, ) -> ActorResult<Bytes>

发送请求并等待响应(显式指定 PayloadType)

Source

pub async fn send_message( &self, target: &ActrId, envelope: RpcEnvelope, ) -> ActorResult<()>

发送单向消息(不等待响应)

§参数
  • target: 目标 Actor ID
  • envelope: 消息信封
§语义

Fire-and-forget:发送后立即返回,不等待响应

Source

pub async fn send_message_with_type( &self, target: &ActrId, payload_type: PayloadType, envelope: RpcEnvelope, ) -> ActorResult<()>

发送单向消息(显式指定 PayloadType)

Source

pub async fn send_media_sample( &self, target: &ActrId, track_id: &str, sample: MediaSample, ) -> ActorResult<()>

发送媒体样本(WebRTC native media)

§参数
  • target: 目标 Actor ID
  • track_id: Media track 标识符
  • sample: 媒体样本数据
§语义
  • 仅支持 OutprocOut(WebRTC)
  • InprocOut 返回 NotImplemented 错误
  • 使用 WebRTC RTCRtpSender 发送,无 protobuf 开销
Source

pub async fn send_data_stream( &self, target: &ActrId, payload_type: PayloadType, data: Bytes, ) -> ActorResult<()>

发送 DataStream(Fast Path 数据流)

§参数
  • target: 目标 Actor ID
  • payload_type: PayloadType (StreamReliable 或 StreamLatencyFirst)
  • data: 序列化后的 DataStream bytes
§语义
  • InprocOut: 通过 mpsc channel 发送
  • OutprocOut: 通过 WebRTC DataChannel 或 WebSocket 发送
