Struct OutputMessageStartedData 

pub struct OutputMessageStartedData {
    pub turn_id: TurnId,
    pub model: Option<String>,
    pub iteration: Option<u32>,
}

Data for output.message.started event

Emitted when the LLM starts generating a response. UI can show a “thinking” indicator until output.message.delta or output.message.completed events arrive.

Fields

turn_id: TurnId

Turn ID this output belongs to

model: Option<String>

Optional model name being used

iteration: Option<u32>

Current iteration number within this turn (1-based). Useful for UI to show progress during multi-step tool-calling flows.
