feat(a2a-nats): add client message_stream per-operation method by yordis · Pull Request #340 · TrogonStack/trogonai

yordis · 2026-06-19T00:43:36Z

Per-op slice of the client handle: message/stream pairs the bootstrap unary call with a JetStream subscription, and threading the prefix + req_id + consumer config by hand at every call site is the kind of footgun the handle exists to hide.

Streaming responses need both the bootstrap RPC and the JetStream subscription wired together on the agent's per-task event subject; combining them on the handle keeps callers from threading the prefix + req_id + consumer config by hand for every stream.

PR Summary

Medium Risk
Introduces a new streaming client entry point over NATS/JetStream and gateway routing; behavior is delegated to existing send_streaming but expands the public API surface for message flows.

Overview
Adds message_stream on A2aClient for the message/stream A2A operation. Callers get a bootstrap SendMessageResponse and a TypedEventStream in one call instead of wiring NATS subjects, req_id, JetStream, and gateway JWT by hand.

The method uses MessageStreamSubject, applies the same direct agent vs gateway ingress overlay as other RPCs, and delegates to send_streaming. It is gated on JetStream-capable client type parameters.

Tests cover default agent subject, gateway-routed subject, and transport error propagation, consistent with existing per-operation handle tests.

Walkthrough

Adds A2aClient::message_stream to handle.rs under a new JetStream-bounded impl block. The method computes the outbound NATS subject, builds a StreamingRequest, and calls send_streaming to return (SendMessageResponse, TypedEventStream). Three unit tests cover agent routing, gateway routing, and transport error propagation.

Changes

A2aClient JetStream Streaming Operation

Layer / File(s)	Summary
`message_stream` imports and implementation `rsworkspace/crates/a2a-nats/src/client/handle.rs`	Imports are extended with JetStream consumer/ack/message types, `TypedEventStream`, `StreamingRequest`, and `send_streaming`. A new `impl<N, J> A2aClient<N, J>` block with `JetStreamGetStream` bounds introduces `message_stream`, which resolves the outbound subject (direct or gateway overlay), constructs a `StreamingRequest` with timeout, request id, and optional gateway caller JWT, and returns `send_streaming`'s result.
`message_stream_op` tests `rsworkspace/crates/a2a-nats/src/client/handle.rs`	Three tests using mock NATS and mock JetStream consumers verify: routing to the agent subject by default, routing through the gateway subject when a gateway ingress JWT is set, and that NATS transport failures surface as `ClientError::Transport`.

Poem

🐇 Hippity-hop through the JetStream flow,
A new message_stream puts on quite a show!
Gateway or direct, the subject is found,
TypedEventStream streams each event around.
Mock consumers confirm the routes are right —
This bunny's streaming code compiles tonight! 🎉
