16//! Common componentry for [NautilusTrader](https://nautilustrader.io).
17//!
18//! The `nautilus-common` crate provides shared components and utilities that form the system foundation for
19//! NautilusTrader applications. This includes the actor system, message bus, caching layer, and other
20//! essential services.
21//!
22//! # NautilusTrader
23//!
24//! [NautilusTrader](https://nautilustrader.io) is an open-source, production-grade, Rust-native
25//! engine for multi-asset, multi-venue trading systems.
26//!
27//! The system spans research, deterministic simulation, and live execution within a single
28//! event-driven architecture, providing research-to-live semantic parity.
29//!
30//! # Feature Flags
31//!
32//! This crate provides feature flags to control source code inclusion during compilation,
33//! depending on the intended use case, i.e. whether to provide Python bindings
34//! for the [nautilus_trader](https://pypi.org/project/nautilus_trader) Python package,
35//! or as part of a Rust only build.
36//!
37//! - `ffi`: Enables the C foreign function interface (FFI) from [cbindgen](https://github.com/mozilla/cbindgen).
38//! - `python`: Enables Python bindings from [PyO3](https://pyo3.rs).
39//! - `defi`: Enables DeFi (Decentralized Finance) support.
40//! - `indicators`: Includes the `nautilus-indicators` crate and indicator utilities.
41//! - `capnp`: Enables [Cap'n Proto](https://capnproto.org/) serialization support.
42//! - `live`: Enables the Tokio async runtime for live trading.
43//! - `tracing-bridge`: Enables the `tracing` subscriber bridge for log integration.
44//! - `extension-module`: Builds the crate as a Python extension module.
