Struct LambdaA2aServerBuilder 

pub struct LambdaA2aServerBuilder { /* private fields */ }

Builder for Lambda A2A handler.

Use .storage(my_storage) to supply a single backend implementing all storage traits. This satisfies ADR-009’s same-backend requirement and enables streaming via durable event store.

Implementations

impl LambdaA2aServerBuilder

pub fn new() -> Self

pub fn executor(self, exec: impl AgentExecutor + 'static) -> Self

pub fn storage<S>(self, storage: S) -> Self

where S: A2aTaskStorage + A2aPushNotificationStorage + A2aEventStore + A2aAtomicStore + Clone + 'static,

Set all storage from a single backend instance.

This is the preferred method — a single struct implementing all storage traits guarantees the same-backend requirement (ADR-009).

pub fn task_storage(self, s: impl A2aTaskStorage + 'static) -> Self

Set task storage individually. Must be paired with event_store/atomic_store for same-backend compliance.

pub fn push_storage(self, s: impl A2aPushNotificationStorage + 'static) -> Self

Set push notification storage individually.

pub fn event_store(self, s: impl A2aEventStore + 'static) -> Self

Set event store individually. Must match task_storage backend.

pub fn atomic_store(self, s: impl A2aAtomicStore + 'static) -> Self

Set atomic store individually. Must match task_storage backend.

pub fn middleware(self, mw: Arc<dyn A2aMiddleware>) -> Self

pub fn build(self) -> Result<LambdaA2aHandler, A2aError>
