//! Transport abstraction layer for bridging gRPC bidirectional streaming with kameo actors.
|
||||
//!
|
||||
//! This module provides a clean separation between the gRPC transport layer and business logic
|
||||
//! by modeling the connection as two linked kameo actors:
|
||||
//!
|
||||
//! - A **transport actor** ([`GrpcTransportActor`]) that owns the gRPC stream and channel,
|
||||
//! forwarding inbound messages to the business actor and outbound messages to the client.
|
||||
//! - A **business logic actor** that receives inbound messages from the transport actor and
|
||||
//! sends outbound messages back through the transport actor.
|
||||
//!
|
||||
//! The [`wire()`] function sets up bidirectional linking between the two actors, ensuring
|
||||
//! that if either actor dies, the other is notified and can shut down gracefully.
|
||||
//!
|
||||
//! # Terminology
|
||||
//!
|
||||
//! - **InboundMessage**: a message received by the transport actor from the channel/socket
|
||||
//! and forwarded to the business actor.
|
||||
//! - **OutboundMessage**: a message produced by the business actor and sent to the transport
|
||||
//! actor to be forwarded to the channel/socket.
|
||||
//!
|
||||
//! # Architecture
|
||||
//!
|
||||
//! ```text
|
||||
//! gRPC Stream ──InboundMessage──▶ GrpcTransportActor ──tell(InboundMessage)──▶ BusinessActor
