Rexilion Engine local Rust-backed execution package

Rexilion Engine

Rexilion Engine is a local Rust-backed execution package with a Python facade.

Target install flow:

pip install rexilion-engine

Minimal local usage:

from rexilion_engine import Engine

engine = Engine()
engine.set_position("BTCUSDT", 0)
report = engine.target_position(
    command_id="cmd-example",
    strategy_id="strategy-example",
    symbol="BTCUSDT",
    target_qty_units=125,
)

For migration checks, Engine.base_engine_plan(...) and BaseEngine.rust_compatibility_plan() report which legacy Python BaseEngine startup steps are Rust-ready versus still Python-backed. They do not start live exchange/provider calls.

Engine.base_engine_local_runtime_plan(...), Engine.datasource_poll_decision(...), Engine.drawdown_decision(...), and Engine.strategy_event_decision(...) expose the Rust-owned local BaseEngine runtime decisions without live network side effects.

The native wheel contains the Rust extension module rexilion_engine._native. If no platform wheel exists, pip may try to build from source and the user will need a compatible Rust/Python build environment.

The Python datasource package surface includes DataProvider.REXILION_TEST, which routes the Rexilion client to https://testapi.rexilion.com/v1/metrics/ while keeping DataProvider.REXILION on the production API host.
