Module axum_adapter 

Axum framework integration for A2A servers.

Provides A2aRouter, which builds an axum::Router that handles all A2A v1.0 methods using the existing RequestHandler.

Quick start

use std::sync::Arc;
use a2a_protocol_server::dispatch::axum_adapter::A2aRouter;
use a2a_protocol_server::RequestHandlerBuilder;

let handler = Arc::new(
    RequestHandlerBuilder::new(MyExecutor)
        .build()
        .expect("build handler"),
);

let app = A2aRouter::new(handler).into_router();

let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();
axum::serve(listener, app).await.unwrap();

Composability

The returned router can be merged with other Axum routes, middleware, and layers:

let app = axum::Router::new()
    .merge(A2aRouter::new(handler).into_router())
    .layer(tower_http::cors::CorsLayer::permissive())
    .route("/custom", get(custom_handler));
