//! Database and messaging infrastructure for [PoseiTrader](http://poseitrader.io).
//!
//! The *infrastructure* crate provides backend database implementations and message bus adapters
//! that enable PoseiTrader to scale from development to production deployments. This includes
//! enterprise-grade data persistence and messaging capabilities:
//!
//! - **Redis integration**: Cache database and message bus implementations using Redis.
//! - **PostgreSQL integration**: SQL-based cache database with comprehensive data models.
//! - **Connection management**: Robust connection handling with retry logic and health monitoring.
//! - **Serialization options**: Support for JSON and MessagePack encoding formats.
//! - **Python bindings**: PyO3 integration for seamless Python interoperability.
//!
//! The crate supports multiple database backends through feature flags, allowing users to choose
//! the appropriate infrastructure components for their specific deployment requirements and scale.
//!
//! # Platform
//!
//! [PoseiTrader](http://poseitrader.io) is an open-source, high-performance, production-grade
//! algorithmic trading platform, providing quantitative traders with the ability to backtest
//! portfolios of automated trading strategies on historical data with an event-driven engine,
//! and also deploy those same strategies live, with no code changes.
//!
//! PoseiTrader's design, architecture, and implementation philosophy prioritizes software correctness and safety at the
//! highest level, with the aim of supporting mission-critical, trading system backtesting and live deployment workloads.
//!
//! # 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 [posei_trader](https://pypi.org/project/posei_trader) Python package,
//! or as part of a Rust only build.
//!
//! - `python`: Enables Python bindings from [PyO3](https://pyo3.rs).
//! - `redis`: Enables the Redis cache database and message bus backing implementations.
//! - `sql`: Enables the SQL models and cache database.
