Microsandbox Rust SDK

A Rust SDK for microsandbox - secure self-hosted sandboxes for executing untrusted code. This SDK allows you to create isolated environments for running code with controlled access to system resources.

Installation

Add this to your Cargo.toml:

[dependencies]
microsandbox = "0.1.0"
tokio = { version = "1", features = ["full"] }

Usage

Simple Python Sandbox Example

use microsandbox::{SandboxOptions, PythonSandbox};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a Python sandbox
    let mut sb = PythonSandbox::create(SandboxOptions::builder().name("test").build()).await?;

    // Run Python code
    let exec = sb.run(r#"name = "Python""#).await?;
    let exec = sb.run(r#"print(f"Hello {name}!")"#).await?;

    // Get the output
    println!("{}", exec.output().await?); // prints Hello Python!

    // Stop the sandbox
    sb.stop().await?;

    Ok(())
}

Using Environment Variables

The SDK will automatically read environment variables:

• MSB_API_KEY - Your API key for authentication
• MSB_SERVER_URL - The URL of the microsandbox server (defaults to http://127.0.0.1:5555)

You can also set these values programmatically:

let sb = PythonSandbox::create(
    SandboxOptions::builder()
        .name("test")
        .api_key("msb_your_api_key")
        .server_url("http://your-server-url:5555")
        .build()
).await?;

Features

• Python Sandbox - Run Python code in a secure sandbox
