Introducing ADK-Rust: A Rust Implementation of Google's Agent Development Kit

[jkmaina]

Hey everyone! 👋

I'm excited to share ADK-Rust - a production-ready implementation of Google's Agent Development Kit in Rust.

Why Rust?
After working extensively with adk-python in developing an ai agent factory at zavora.ai, I wanted to bring the same powerful agent development patterns to the Rust ecosystem, targeting use cases where:

Performance is critical - Rust's zero-cost abstractions and memory safety
Deployment size matters - Single binary with no runtime dependencies
Systems-level integration - Embedded systems, edge computing, IoT
Concurrency at scale - Rust's async/await with tokio
Features
ADK-Rust maintains API parity with the Python ADK where possible:

✅ Model-agnostic - Gemini, OpenAI, Anthropic, DeepSeek support
✅ Multiple agent types - LlmAgent, SequentialAgent, ParallelAgent, LoopAgent
✅ Tool support - Built-in tools (Google Search, Code Execution) + custom tools
✅ MCP support - Model Context Protocol integration
✅ Sessions & Memory - InMemorySessionService, DatabaseSessionService
✅ Streaming - Full streaming support for real-time responses
✅ Telemetry - OpenTelemetry integration for tracing/metrics
✅ A2A Protocol - Agent-to-Agent communication

Quick Example

use adk_rust::prelude::*;

#[tokio::main]
async fn main() -> Result<()> {
    let agent = LlmAgentBuilder::new()
        .name("my_agent")
        .model(GeminiModel::new("gemini-2.0-flash")?)
        .instruction("You are a helpful assistant.")
        .build()?;

    let response = agent.run("Hello!").await?;
    println!("{}", response);
    Ok(())
}

Looking for Feedback
I'd love to hear from the community:

What features from adk-python would you prioritize?
Any interest in contributing or testing?
Use cases where a Rust implementation would be valuable?
This is an independent community project, not officially affiliated with Google, but designed to be compatible with the ADK ecosystem.
