generate method
Server-streaming: emits one LLMStreamEvent per generated token until is_final=true. Cancellation aborts the underlying generation via the existing rac_llm_cancel() C ABI.
Tool-driven streaming is not supported on this entry point even when options.tool_calling is populated. Use the non-streaming tool-session generation path for tool calling.
Implementation
$async.Future<LLMStreamEvent> generate(
$pb.ClientContext? ctx, LLMGenerateRequest request) =>
_client.invoke<LLMStreamEvent>(
ctx, 'LLM', 'Generate', request, LLMStreamEvent());
