The user’s business logic entry point.

Implement this trait to handle incoming messages and cancellation requests. The executor returns a stream of events (status updates, artifact updates, messages, or task objects).

Required Methods

fn execute( &self, ctx: ExecutorContext, ) -> BoxStream<'static, Result<StreamResponse, A2AError>>

Execute a message. Returns a stream of events.

fn cancel( &self, ctx: ExecutorContext, ) -> BoxStream<'static, Result<StreamResponse, A2AError>>

Cancel an in-progress task. Returns a stream of events.

In older versions of Rust, dyn compatibility was called "object safety".
