Module server

Expand description

Server framework for implementing A2A agents.

Modules§

agent_card: Agent card HTTP handlers (static, dynamic, and caching utilities).
builder: Builder for RequestHandler.
call_context: Call context for server-side interceptors.
dispatch: HTTP dispatch layer — JSON-RPC and REST routing.
error: Server-specific error types.
executor: Agent executor trait.
handler: Core request handler — protocol logic layer.
interceptor: Server-side interceptor chain.
metrics: Metrics hooks for observing handler activity.
push: Push notification configuration storage and delivery.
request_context: Request context passed to the AgentExecutor.
store: Task storage backend.
streaming: Streaming infrastructure for SSE responses and event queues.

CallContext: Metadata about the current server-side method call.
CorsConfig: CORS configuration for A2A dispatchers.
DynamicAgentCardHandler: Serves a dynamically generated AgentCard as a JSON HTTP response.
EventQueueManager: Manages event queues for active tasks.
HttpPushSender: HTTP-based PushSender using hyper.
InMemoryPushConfigStore: In-memory PushConfigStore backed by a HashMap.
InMemoryQueueReader: In-memory EventQueueReader backed by an mpsc channel receiver.
InMemoryQueueWriter: In-memory EventQueueWriter backed by an mpsc channel sender.
InMemoryTaskStore: In-memory TaskStore backed by a HashMap under a RwLock.
JsonRpcDispatcher: JSON-RPC 2.0 request dispatcher.
RequestContext: Context for a single agent execution request.
RequestHandler: The core protocol logic handler.
RequestHandlerBuilder: Fluent builder for RequestHandler.
RestDispatcher: REST HTTP request dispatcher.
ServerInterceptorChain: An ordered chain of ServerInterceptor instances.
StaticAgentCardHandler: Serves a pre-serialized AgentCard as a JSON HTTP response with caching.
TaskStoreConfig: Configuration for InMemoryTaskStore.

CORS_ALLOW_ALL: CORS Access-Control-Allow-Origin header value for public agent cards.
