Enum StreamResponse 

#[non_exhaustive]
pub enum StreamResponse {
    Task(Task),
    Message(Message),
    StatusUpdate(TaskStatusUpdateEvent),
    ArtifactUpdate(TaskArtifactUpdateEvent),
}

A single event payload in an A2A streaming response.

Discriminated by field presence (untagged oneof). Exactly one of task, message, statusUpdate, or artifactUpdate is present.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Task(Task)

A complete task object (initial response before streaming begins).

Message(Message)

A complete message (returned synchronously for short responses).

StatusUpdate(TaskStatusUpdateEvent)

A task state change event.

ArtifactUpdate(TaskArtifactUpdateEvent)

An artifact delivery event.
