caravan-rpc 0.0.1

Runtime SDK for the Caravan application-definition compiler. Pre-release placeholder.

caravan-rpc (Python) — Pre-release placeholder

Runtime SDK for the Caravan application-definition compiler.

Status: 0.0.1 pre-release placeholder. This release reserves the PyPI name. The functional SDK lands at 0.1.0.

What is Caravan?

Caravan is an application-definition compiler. The same source code deploys across packaging (inproc / container / lambda) × placement (compose / Fargate / Lambda / Batch) × composition (oss-local / cloud-managed) axes by yaml-line changes alone — no source-code edits.

When 0.1.0 ships

from caravan_rpc import wagon, provide, client

@wagon
class LLMExtraction:
    def extract(self, ocr_text: str) -> dict: ...

# provider side
class GeminiExtractor(LLMExtraction):
    def extract(self, ocr_text):
        ...

provide(LLMExtraction, GeminiExtractor())

# caller side — dispatches inproc / http / lambda per CARAVAN_RPC_PEERS
extractor = client(LLMExtraction)
result = extractor.extract(text)

The 0.0.1 placeholder provides import-clean stubs but client() raises NotImplementedError — it's not functional yet.

Roadmap

• 0.0.1 (this release): reserve PyPI name, import-clean stubs.
• 0.1.0: functional runtime. @wagon, provide, client work with CARAVAN_RPC_PEERS env-var dispatch. See development_plan.md milestones B0–M3.
