Struct ToolCallRouter 

pub struct ToolCallRouter { /* private fields */ }

Hybrid tool-call router backed by a local FunctionGemma model.

Created once at session start; shared via Arc across prompt calls.

Implementations

impl ToolCallRouter

pub fn from_config(config: &ToolRouterConfig) -> Result<Option<Self>>

Construct from a ToolRouterConfig.

Returns None if the router is disabled or missing required paths.

pub async fn maybe_reformat( &self, response: CompletionResponse, tools: &[ToolDefinition], ) -> CompletionResponse

Conditionally reformat a CompletionResponse.

• If the response already contains ContentPart::ToolCall entries, return it unchanged (zero overhead path).
• If the response is text-only, run FunctionGemma to convert the text into structured tool calls.
• On any internal error, return the original response unchanged (safe degradation — the router never breaks existing functionality).
