//! [NautilusTrader](https://nautilustrader.io) adapter for the [Lighter](https://lighter.xyz) DEX.
//!
//! The `nautilus-lighter` crate provides integration with the Lighter protocol for trading
//! perpetual futures and spot markets on the Lighter and Robinhood Chain deployments.
//!
//! # 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.
//!
//! - `examples`: Enables the crate's example binaries.
//! - `extension-module`: Builds as a Python extension module.
//! - `fuzz`: Enables libFuzzer integration for fuzz targets.
//! - `high-precision` (default): Enables
//!   [high-precision mode](https://nautilustrader.io/docs/nightly/getting_started/installation/#precision-mode)
//!   to use 128-bit value types.
//! - `python`: Enables Python bindings from [PyO3](https://pyo3.rs).
//!
//! Python bindings for the Lighter adapter are intentionally scoped to configuration,
//! enums, factory wiring, and integrator revocation. Data and execution
//! clients are consumed directly through the Rust trait surface.
//!
//! # Integrator attribution
//!
//! On Lighter Mainnet, submitted create and modify order transactions from Plus and Premium
//! accounts carry the NautilusTrader integrator account index in Lighter's `L2TxAttributes`. This
//! helps us gauge real usage of the integration and prioritize ongoing maintenance. Maker and taker
//! integrator fees are set to zero, so attribution adds no trading cost. All other account tiers,
//! sessions without an account snapshot, Lighter Testnet, and both Robinhood environments leave
//! `L2TxAttributes` empty.
//!
//! Lighter requires an `ApproveIntegrator` approval before these attributes can be attached to
//! Lighter Mainnet orders. During startup, the execution client submits the required zero-fee
//! approval for a configured Plus or Premium L2 account. Other Lighter account tiers, sessions
//! without an account snapshot, Lighter Testnet, and Robinhood clients do not submit an approval.
//!
//! Robinhood Mainnet instead applies the `NAUTILUS` referral to the account's public L1 address
//! during execution-client startup. Application failures log a warning and do not block trading.
//! Robinhood Testnet does not apply a referral. See the [Lighter integration guide](https://nautilustrader.io/docs/nightly/integrations/lighter/#integrator-attribution)
//! for attribution and revocation details.
