16//! System-level components and orchestration for [NautilusTrader](https://nautilustrader.io).
17//!
18//! The `nautilus-system` crate provides the core system architecture for orchestrating trading systems,
19//! including the kernel that manages all engines, configuration management,
20//! and system-level factories for creating components:
21//!
22//! - `NautilusKernel` - Core system orchestrator managing engines and components.
23//! - `NautilusKernelConfig` - Configuration for kernel initialization.
24//! - System builders and factories for component creation.
25//!
26//! # NautilusTrader
27//!
28//! [NautilusTrader](https://nautilustrader.io) is an open-source, production-grade, Rust-native
29//! engine for multi-asset, multi-venue trading systems.
30//!
31//! The system spans research, deterministic simulation, and live execution within a single
32//! event-driven architecture, providing research-to-live semantic parity.
33//!
34//! # Feature Flags
35//!
36//! This crate provides feature flags to control source code inclusion during compilation,
37//! depending on the intended use case, i.e. whether to provide Python bindings
38//! for the [nautilus_trader](https://pypi.org/project/nautilus_trader) Python package,
39//! or as part of a Rust only build.
40//!
41//! - `streaming`: Enables `persistence` dependency for streaming configuration.
42//! - `python`: Enables Python bindings from [PyO3](https://pyo3.rs) (auto-enables `streaming`).
43//! - `defi`: Enables DeFi (Decentralized Finance) support.
44//! - `live`: Enables live trading mode dependencies.
45//! - `tracing-bridge`: Enables the `tracing` subscriber bridge for log integration.
46//! - `extension-module`: Builds the crate as a Python extension module.
