🦀 cc-sdk v0.6.0 - Rust SDK for Claude Code

**🎉 100% Feature Parity with Python claude-agent-sdk v0.1.14!** | **🌐 WebSocket Transport (v0.6.0)**

[](https://crates.io/crates/cc-sdk) [](https://docs.rs/cc-sdk)

**[cc-sdk](./claude-code-sdk-rs)** is the official Rust SDK for Claude Code CLI, providing:

• 📥 Auto CLI Download - Automatically downloads Claude Code CLI if not found
• 📁 File Checkpointing - Rewind file changes to any conversation point
• 📊 Structured Output - JSON schema validation for responses
• 🔧 Full Control Protocol - Permissions, hooks, MCP servers
• 💰 Budget Control - max_budget_usd and fallback_model support
• 🏖️ Sandbox - Bash isolation for filesystem/network

use cc_sdk::{query, ClaudeCodeOptions};
use futures::StreamExt;

#[tokio::main]
async fn main() -> cc_sdk::Result<()> {
    let options = ClaudeCodeOptions::builder()
        .model("claude-opus-4-5-20251101")  // Latest Opus 4.5
        .auto_download_cli(true)             // Auto-download CLI
        .max_budget_usd(10.0)                // Budget limit
        .build();

    let mut stream = query("Hello, Claude!", Some(options)).await?;
    while let Some(msg) = stream.next().await {
        println!("{:?}", msg?);
    }
    Ok(())
}
