rustbox 0.3.0

Official Python SDK for Rustbox - run untrusted code in a kernel-enforced sandbox.

🐍 Rustbox Python SDK

Async-first via httpx. One required dep. Typed exceptions.

⚠️ Async-only. All public methods are coroutines. Wrap with asyncio.run() from sync code.

🚀 Install

pip install rustbox        # or: uv pip install rustbox / poetry add rustbox

⚡ Quickstart

import asyncio, os
from rustbox import Rustbox

async def main():
    client = Rustbox(os.environ["RUSTBOX_API_KEY"])
    result = await client.run(language="python", code="print('hello')")
    print(result["verdict"], result["stdout"])  # AC hello

asyncio.run(main())

run() submits, waits for sync completion, polls if needed, returns the verdict.

Profiles

# Judge profile (default) - short evaluation runs, no egress proxy.
await client.run("python", "print(1)")

# Agent profile - longer jobs, egress proxy on, per-key byte budget.
# Requires a non-trial API key.
await client.run("python", "...", profile="agent")

🔒 Errors

from rustbox import (
    RustboxAuthError, RustboxRateLimitError, RustboxServerError, RustboxError,
)

try:
    await client.run("python", "...")
except RustboxAuthError:       pass  # 401/403
except RustboxRateLimitError:  pass  # 429 - back off
except RustboxServerError:     pass  # 5xx - retry
except RustboxError:           pass  # other

🧰 Full API

Rustbox(
    api_key: str,
    base_url: str = DEFAULT_BASE_URL,
    *,
    timeout_secs: float = 65.0,
    max_retries: int = 2,
)

await client.run(
    language: str,
    code: str,
    stdin: str = "",
    profile: Literal["judge", "agent"] | None = None,
)  # -> dict

await client.submit(
    language, code, stdin="",
    profile=None, wait=False,
    idempotency_key=None,
)  # -> dict

await client.get_result(job_id)    # -> dict
await client.get_languages()       # -> list[str]
await client.get_health()          # -> dict
await client.get_ready()           # -> dict
await client.aclose()              # close httpx connection pool

🧪 Tests

cd python
uv pip install pytest pytest-asyncio respx httpx
python -m pytest -q

respx mocks httpx. No network.
