Enum StreamedAssistantContent

}

Describes responses from a streamed provider response which is either text, a tool call or a final usage response.

Variants

Text(Text)

Text delta emitted by the assistant.

ToolCall

Complete tool call emitted by the assistant.

Fields

tool_call: ToolCall

internal_call_id: String

Rig-generated unique identifier for this tool call. Use this to correlate with ToolCallDelta events.

ToolCallDelta

Partial tool call data emitted by the assistant.

Fields

id: String

Provider-supplied tool call ID.

internal_call_id: String

Rig-generated unique identifier for this tool call.

content: ToolCallDeltaContent

Reasoning(Reasoning)

Complete reasoning block emitted by the assistant.

ReasoningDelta

Partial reasoning text emitted by the assistant.

Fields

id: Option<String>

Provider-supplied reasoning block ID, when present.

reasoning: String

Partial reasoning text.

Final(R)

Final provider response object, if yielded by the provider stream.

Unknown(Value)

A provider-native output item rig does not model, preserved verbatim — e.g. an OpenAI Responses hosted-tool result (web_search_call, file_search_call, computer_call, code_interpreter_call). It is yielded to the consumer for inspection/forwarding but is not added to the accumulated assistant message or persisted history. Kept last because the enum is #[serde(untagged)] and a raw Value matches anything, so earlier (typed) variants must be tried first.
