#![cfg_attr(coverage_nightly, coverage(off))]
//! Generic file ranking system for prioritizing code analysis
//!
//! This module provides a flexible ranking framework that can sort files by
//! various metrics including complexity, technical debt, code churn, and more.
//! It uses parallel processing and caching to efficiently rank large codebases,
//! helping developers focus on the most problematic areas first.
//!
//! # Architecture
//!
//! The ranking system consists of:
//! - **`FileRanker` Trait**: Defines how to compute and format rankings
//! - **`RankingEngine`**: Generic engine that applies rankers with caching
//! - **Built-in Rankers**: Complexity, TDG, churn, and composite rankers
//! - **Parallel Processing**: Uses Rayon for efficient multi-core ranking
//!
//! # Ranking Strategies
//!
//! - **Complexity Ranking**: Sorts by cyclomatic/cognitive complexity
//! - **TDG Ranking**: Uses Technical Debt Gradient scores
//! - **Churn Ranking**: Prioritizes frequently changed files
//! - **Composite Ranking**: Combines multiple metrics with weights
//!
//! # Example
//!
//! ```ignore
//! use pmat::services::ranking::{RankingEngine, ComplexityRanker};
//! use std::path::PathBuf;
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! // Create a complexity-based ranker
//! let ranker = ComplexityRanker::new();
//! let engine = RankingEngine::new(ranker);
//!
//! // Rank files by complexity
//! let files = vec![
//! PathBuf::from("src/main.rs"),
//! PathBuf::from("src/lib.rs"),
//! PathBuf::from("src/complex_module.rs"),
//! ];
//!
//! let top_5 = engine.rank_files(&files, 5).await;
//!
//! for (i, (file, score)) in top_5.iter().enumerate() {
//! println!("{}. {} (complexity: {})", i + 1, file, score);
//! }
//! # Ok(())
//! # }
//! ```ignore
