pub struct GenAiResponseRecorder;

Available on crate features telemetry and genai-semconv only.

Records response-time attributes on the current span.

Call after receiving the model response to populate response model, finish reasons, and token usage.

Example

use adk_telemetry::semconv::GenAiResponseRecorder;
use adk_telemetry::LlmUsage;

// After receiving model response:
GenAiResponseRecorder::record_response_model("gemini-2.5-flash-001");
GenAiResponseRecorder::record_finish_reasons(&["stop"]);
GenAiResponseRecorder::record_usage(&LlmUsage {
    input_tokens: 100,
    output_tokens: 50,
    total_tokens: 150,
    ..Default::default()
});

impl GenAiResponseRecorder

pub fn record_response_model(model: &str)

Record the response model (may differ from request model).

pub fn record_finish_reasons(reasons: &[&str])
