ADK Rust Realtime Voice

Overview

Build low-latency bidirectional audio flows with explicit session/event handling.

Workflow

1. Select provider backend and audio format early.
2. Validate session configuration and VAD settings.
3. Handle client/server events with explicit match branches.
4. Verify tool call lifecycle in realtime paths.
5. Configure interruption detection (Manual or Automatic).
6. Use SessionUpdateConfig for mid-session context mutation (swap instructions/tools without dropping the call).

Guardrails

1. Fail fast on unsupported modalities.
2. Keep audio encoding assumptions explicit.
3. Add coverage for cancellation, interruptions, and error events.
4. Use ContextMutationOutcome to handle provider differences (OpenAI: Applied, Gemini: RequiresResumption).
