Crate nautilus_core

Core foundational types and utilities for PoseiTrader.

The core crate is designed to be lightweight, efficient, and to provide zero-cost abstractions wherever possible. It supplies the essential building blocks used across the PoseiTrader ecosystem, including:

• Time handling and atomic clock functionality.
• UUID generation and management.
• Mathematical functions and interpolation utilities.
• Correctness validation functions.
• Serialization traits and helpers.
• Cross-platform environment utilities.
• Abstractions over common collections.

Platform

PoseiTrader 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 Python package, or as part of a Rust only build.

• ffi: Enables the C foreign function interface (FFI) from cbindgen.
• python: Enables Python bindings from PyO3.
