Crate nautilus_pyo3 

Python bindings aggregator crate for NautilusTrader.

The nautilus-pyo3 crate collects the Python bindings generated across the NautilusTrader workspace and re-exports them through a single shared library that can be included in binary wheels.

NautilusTrader

NautilusTrader is an open-source, production-grade, Rust-native engine for multi-asset, multi-venue trading systems.

The system spans research, deterministic simulation, and live execution within a single event-driven architecture, providing research-to-live semantic parity.

Feature Flags

This crate is primarily intended to be built for Python via maturin and therefore provides a broad set of feature flags to toggle bindings and optional dependencies:

• extension-module: Builds the crate as a Python extension module (automatically enabled by maturin).
• ffi: Enables the C foreign function interface (FFI) support in dependent crates.
• high-precision: Uses 128-bit value types throughout the workspace.
• cython-compat: Adjusts the module name so it can be imported from Cython generated code.
• postgres: Enables PostgreSQL (sqlx) back-ends in dependent crates.
• redis: Enables Redis based infrastructure in dependent crates.
• hypersync: Enables hypersync support (fast parallel hash maps) where available.
• tracing-bridge: Enables the tracing subscriber bridge for log integration.
• defi: Enables DeFi (Decentralized Finance) support including blockchain adapters.
