Question 1

How to set up realtime voice agents in ADK-Rust?

Accepted Answer

Use the adk-realtime crate with providers like OpenAI Realtime API; enable features like 'realtime-openai', configure audio streaming, and implement VAD. Examples in the adk-playground repo show full setups with bidirectional audio.

Question 2

ADK-Rust vs LangChain: which is better for Rust projects?

Accepted Answer

ADK-Rust is native to Rust, offering type safety and performance benefits, while LangChain is Python-centric with a larger ecosystem. For Rust-based AI agents, ADK-Rust is preferable due to its integrated features and Rust-specific optimizations.

Question 3

What LLM providers does ADK-Rust support?

Accepted Answer

It supports Gemini, OpenAI, Anthropic, DeepSeek, Groq, Ollama, and several OpenAI-compatible providers like Fireworks AI and Together AI, all through a unified API with streaming and function calling, as listed in the Multi-Provider Support section.

Question 4

Is ADK-Rust production ready?

Accepted Answer

Yes, it includes production features such as session management, encryption, observability with OpenTelemetry, and security guardrails. The framework is actively maintained and versioned, with a focus on stability for deployment.

Question 5

How to add custom tools with the #[tool] macro?

Accepted Answer

Annotate a Rust function with #[tool]; it auto-generates the tool schema from the function's arguments and doc comments. Example in the README shows a weather tool with zero boilerplate code.

Question 6

Can I use ADK-Rust for local inference without cloud APIs?

Accepted Answer

Yes, via the adk-mistralrs crate for local models with ISQ quantization, but it requires git dependencies and builds with optional Metal or CUDA features, adding complexity compared to cloud providers.

Question 7

What are the system requirements for running ADK-Rust?

Accepted Answer

Requires Rust 1.85 or later, and specific features need additional setup like WebDriver for browser automation or Ollama for local models. API keys are needed for cloud providers, as detailed in the environment variable examples.
