Struct JsonRpcDispatcher 

pub struct JsonRpcDispatcher { /* private fields */ }

JSON-RPC 2.0 request dispatcher.

Routes incoming JSON-RPC requests to the underlying RequestHandler. Optionally applies CORS headers to all responses.

Also serves the agent card at GET /.well-known/agent.json so that JSON-RPC servers can participate in agent card discovery (spec §8.3).

Implementations

impl JsonRpcDispatcher

pub fn new(handler: Arc<RequestHandler>) -> JsonRpcDispatcher

Creates a new dispatcher wrapping the given handler with default configuration.

pub fn with_config( handler: Arc<RequestHandler>, config: DispatchConfig, ) -> JsonRpcDispatcher

Creates a new dispatcher with the given configuration.

pub fn with_cors(self, cors: CorsConfig) -> JsonRpcDispatcher

Sets CORS configuration for this dispatcher.

When set, all responses will include CORS headers, and OPTIONS preflight requests will be handled automatically.

pub async fn dispatch( &self, req: Request<Incoming>, ) -> Response<BoxBody<Bytes, Infallible>>

Dispatches a JSON-RPC request and returns an HTTP response.

For SendStreamingMessage and SubscribeToTask, the response uses SSE (text/event-stream). All other methods return JSON.

JSON-RPC errors are always returned as HTTP 200 with an error body.
