Enum CompletionResponse 

pub enum CompletionResponse {
    Text(String),
    ToolUse {
        blocks: Vec<ToolUseBlock>,
        assistant_content: String,
    },
}

The result of a complete_with_tools call.

Either the LLM produced a final text answer or it wants to call one or more tools.

Variants

Text(String)

The LLM produced a final text response (stop_reason “end_turn” / finish_reason “stop”).

ToolUse

The LLM wants to invoke tools (stop_reason “tool_use” / finish_reason “tool_calls”).

Carries both the parsed tool-use blocks and the raw assistant content string. The dispatch loop must push an Assistant message with assistant_content into history BEFORE appending tool result messages — both Anthropic and OpenAI require the assistant’s tool-call turn to precede the corresponding tool_result messages.

Fields

blocks: Vec<ToolUseBlock>

Parsed tool-use blocks to dispatch.

assistant_content: String

Raw assistant content (JSON array string for Anthropic, or tool_calls JSON for OpenAI). Stored verbatim so the dispatch loop can reconstruct the assistant message.
