Struct A2aRouter 

pub struct A2aRouter { /* private fields */ }

Builder for an Axum Router that serves all A2A v1.0 protocol methods.

Wraps an existing RequestHandler — all business logic, storage, and interceptors are inherited. This is a thin HTTP routing layer only.

Implementations

impl A2aRouter

pub fn new(handler: Arc<RequestHandler>) -> A2aRouter

Creates a new A2aRouter wrapping the given handler.

pub const fn with_config( handler: Arc<RequestHandler>, config: DispatchConfig, ) -> A2aRouter

Creates a new A2aRouter with custom dispatch configuration.

pub fn into_router(self) -> Router
