Enum A2AError

pub enum A2AError {
    IllegalTransition {
        from: TaskLifecycle,
        to: TaskLifecycle,
    },
    ParseError(String),
    NetworkNotWired(String),
}

Expand description

Error returned by A2A task lifecycle operations. Replaces the former A2AStub (the spec is now sufficiently stable for the task state machine; the wire format may still evolve). The A2AStub type is kept as an alias for backward compatibility with the handle_a2a_request function (which is about the network call, not the state machine).

Variants§

§

IllegalTransition

An illegal state transition was attempted (e.g. Completed -> Working). The from and to fields name the states.

Fields

§from: TaskLifecycle

§to: TaskLifecycle

§

ParseError(String)

A parse error (Agent Card JSON, response JSON, etc.).

§

NetworkNotWired(String)

The network call is not yet wired (the adapter intentionally does not own an HTTP client; the transport is the agent’s upstream). This is the only remaining “stub” surface.
