16//! Data persistence and storage management for [NautilusTrader](https://nautilustrader.io).
17//!
18//! The `nautilus-persistence` crate provides data persistence capabilities for storing and retrieving
19//! trading data, state, and configuration.
20//!
21//! # NautilusTrader
22//!
23//! [NautilusTrader](https://nautilustrader.io) is an open-source, production-grade, Rust-native
24//! engine for multi-asset, multi-venue trading systems.
25//!
26//! The system spans research, deterministic simulation, and live execution within a single
27//! event-driven architecture, providing research-to-live semantic parity.
28//!
29//! # Feature Flags
30//!
31//! This crate provides feature flags to control source code inclusion during compilation,
32//! depending on the intended use case, i.e. whether to provide Python bindings
33//! for the [nautilus_trader](https://pypi.org/project/nautilus_trader) Python package,
34//! or as part of a Rust only build.
35//!
36//! - `cloud`: Enables cloud storage backends (S3, Azure, GCP, HTTP) via `object_store`.
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) (auto-enables `cloud`).
39//! - `high-precision`: Enables [high-precision mode](https://nautilustrader.io/docs/nightly/getting_started/installation#precision-mode) to use 128-bit value types.
40//! - `extension-module`: Builds the crate as a Python extension module.
