Crate nautilus_persistence 

Data persistence and storage management for NautilusTrader.

The nautilus-persistence crate provides data persistence capabilities for storing and retrieving trading data, state, and configuration.

NautilusTrader

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

• cloud: Enables cloud storage backends (S3, Azure, GCP, HTTP) via object_store.
• defi: Enables DeFi (Decentralized Finance) support.
• extension-module: Builds as a Python extension module.
• high-precision: Enables high-precision mode to use 128-bit value types.
• python: Enables Python bindings from PyO3 and auto-enables cloud.
