Enum Message 

pub enum Message {
    System(SystemMessage),
    User(UserMessage),
    Assistant(AssistantMessage),
    Result(ResultMessage),
    StreamEvent(StreamEvent),
    RateLimitEvent(RateLimitEvent),
}

A single NDJSON message read from the Claude CLI stdout.

Deserialized via #[serde(tag = "type")] so the "type" field selects the variant.

Variants

System(SystemMessage)

Session metadata emitted once at the start.

User(UserMessage)

Echo of a user turn (our input reflected back).

Assistant(AssistantMessage)

A model response turn.

Result(ResultMessage)

Final summary after the conversation completes.

StreamEvent(StreamEvent)

A raw API streaming event (only when --include-partial-messages).

RateLimitEvent(RateLimitEvent)

Rate limit status information.
