helen-rust

Helen language Rust runtime — Python bridge (M11).

Import and call Helen agents/functions from Python:

import helen_rust                      # auto-installs the .helen import hook
from translator import SumAgent        # translator.helen in sys.path

agent = SumAgent()
agent(10, 20)                          # 30
await agent.async_call(10, 20)         # 30 (executor thread)

# Direct API
from helen_rust import load_agent
native = load_agent("translator.helen", "SumAgent")
native(a=15, b=25)                     # 40

Also exposes parse_check(source) -> list[str] (semantic error codes), eval_helen(source, globals), and helen_agent/helen_module decorators.

Built with maturin: maturin develop --release (development) or pip install helen-rust (wheel).
