//! ML Performance Metrics
//!
//! This module provides comprehensive metrics for evaluating trading strategies
//! and machine learning models, including:
//!
//! - **Sharpe Ratio**: Risk-adjusted return metric
//! - **Future metrics**: Sortino ratio, Calmar ratio, Information ratio, etc.
//!
//! # Examples
//!
//! ```rust
//! use ml::metrics::sharpe::calculate_sharpe_ratio;
//!
//! let daily_returns = vec![0.01, -0.005, 0.02, 0.015, -0.01];
//! let sharpe = calculate_sharpe_ratio(&daily_returns, 0.02, 252.0).unwrap();
//! println!("Sharpe Ratio: {:.2}", sharpe);
//! ```

pub mod sharpe;

// Re-export commonly used functions
pub use sharpe::{calculate_sharpe_ratio, calculate_sharpe_ratio_default};
