//! Data serialization and format conversion for [NautilusTrader](https://nautilustrader.io).
//!
//! The `nautilus-serialization` crate provides data serialization capabilities for converting
//! trading data between different formats including Apache Arrow and Cap'n Proto.
//! This enables efficient data storage, retrieval, and interoperability across different systems:
//!
//! - **Apache Arrow integration**: Schema definitions and encoding/decoding for market data types.
//! - **Parquet file operations**: High-performance columnar storage for historical data analysis.
//! - **Record batch processing**: Efficient batch operations for time-series data.
//! - **Schema management**: Type-safe schema definitions with metadata preservation.
//! - **Cross-format conversion**: Data interchange between Arrow, Cap'n Proto, and native types.
//! - **Cap'n Proto serialization**: Zero-copy, schema-based serialization for efficient data interchange (requires `capnp` feature).
//! - **SBE decode utilities**: Zero-copy cursor and shared decode errors for SBE parsers (requires `sbe` feature).
//!
//! # NautilusTrader
//!
//! [NautilusTrader](https://nautilustrader.io) 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 provides feature flags to control source code inclusion during compilation,
//! depending on the intended use case, i.e. whether to provide Python bindings
//! for the [nautilus_trader](https://pypi.org/project/nautilus_trader) Python package,
//! or as part of a Rust only build.
//!
//! - `arrow`: Enables Apache Arrow schema definitions and RecordBatch encoding/decoding.
//! - `display`: Enables display-friendly Arrow encoders for market data (requires `arrow`).
//! - `python`: Enables Python bindings from [PyO3](https://pyo3.rs).
//! - `high-precision`: Enables [high-precision mode](https://nautilustrader.io/docs/nightly/getting_started/installation#precision-mode) to use 128-bit value types.
//! - `extension-module`: Builds the crate as a Python extension module.
//! - `capnp`: Enables [Cap'n Proto](https://capnproto.org/) serialization support.
//! - `sbe`: Enables generic SBE (Simple Binary Encoding) decode utilities.
//!
//! **Warning:** SBE and Cap'n Proto schemas are not yet stable and may break between releases.
