16//! Core foundational types and utilities for [PoseiTrader](http://poseitrader.io).
17//!
18//! The *core* crate is designed to be lightweight, efficient, and to provide zero-cost abstractions
19//! wherever possible. It supplies the essential building blocks used across the PoseiTrader
20//! ecosystem, including:
21//!
22//! - Time handling and atomic clock functionality.
23//! - UUID generation and management.
24//! - Mathematical functions and interpolation utilities.
25//! - Correctness validation functions.
26//! - Serialization traits and helpers.
27//! - Cross-platform environment utilities.
28//! - Abstractions over common collections.
29//!
30//! # Platform
31//!
32//! [PoseiTrader](http://poseitrader.io) is an open-source, high-performance, production-grade
33//! algorithmic trading platform, providing quantitative traders with the ability to backtest
34//! portfolios of automated trading strategies on historical data with an event-driven engine,
35//! and also deploy those same strategies live, with no code changes.
36//!
37//! PoseiTrader's design, architecture, and implementation philosophy prioritizes software correctness and safety at the
38//! highest level, with the aim of supporting mission-critical, trading system backtesting and live deployment workloads.
39//!
40//! # Feature flags
41//!
42//! This crate provides feature flags to control source code inclusion during compilation,
43//! depending on the intended use case, i.e. whether to provide Python bindings
44//! for the [posei_trader](https://pypi.org/project/posei_trader) Python package,
45//! or as part of a Rust only build.
46//!
47//! - `ffi`: Enables the C foreign function interface (FFI) from [cbindgen](https://github.com/mozilla/cbindgen).
48//! - `python`: Enables Python bindings from [PyO3](https://pyo3.rs).
