Trait Implementations

impl ProtocolHandler for GoogleHandler

fn endpoint_path(&self) -> &str

URL path for the API endpoint (appended to the base URL).

fn auth_headers(&self, _api_key: &str) -> Vec<(String, String)>

Build HTTP headers for authentication.

fn build_request_body(&self, req: &ApiRequest) -> Value

Build the JSON request body from unified ApiRequest.

fn parse_response(&self, body: &str) -> Result<ApiResponse, InferenceError>

Parse a complete (non-streaming) response body into ApiResponse.

fn parse_stream_event(&self, _event_type: &str, _data: &str) -> Vec<StreamEvent>

Parse a single SSE line into StreamEvents (for streaming responses). Returns multiple events when a single SSE chunk contains multiple tool calls.

fn build_messages( &self, messages: &[Message], prompt: &str, context: Option<&str>, images: Option<&[ContentBlock]>, ) -> (Vec<Value>, Option<String>)

Convert conversation Messages to this protocol’s message format.

fn build_tools(&self, tools: &[Value]) -> Vec<Value>

Convert tool definitions to this protocol’s format.

fn supports_streaming(&self) -> bool

Whether this protocol supports streaming.

fn supports_video(&self) -> bool

Whether this protocol accepts video content blocks natively on the generation endpoint. Defaults to false. When a request carries a video block and the selected protocol returns false, RemoteBackend::execute_request rejects the call with InferenceError::UnsupportedMode rather than silently downgrading the video to a text placeholder.

fn supports_audio(&self) -> bool

Whether this protocol accepts audio content blocks natively. Same contract as [supports_video] — false means the remote backend pre-check returns UnsupportedMode instead of silently stringifying the audio reference.

fn protocol_name(&self) -> &'static str

Backend identifier used in UnsupportedMode error messages. Handlers override to something recognizable (e.g. “openai”, “anthropic-messages-v1”).

fn supports_thinking(&self) -> bool

Whether this protocol supports extended thinking.
