# CLI Argument Parsing - clap is the gold standard
# 13.7k GitHub stars, excellent docs, derive macros, shell completions
clap = { version = "4", features = ["derive", "env", "unicode"] }

# TUI Framework - Ratatui is the actively maintained successor to tui-rs
# Cross-platform via crossterm backend, 23k+ GitHub stars
# Pinned to 0.28.x for Rust 1.85 MSRV compatibility
ratatui = { version = "0.28", default-features = false, features = ["crossterm"] }

# Terminal Backend - MUST use crossterm for Windows support
# termion is Unix-only, termwiz is more complex
crossterm = "0.28"

# Hashing - BLAKE3 is optimal for file deduplication
# 2.8-10x faster than SHA-256, parallel processing, cryptographically secure
# Multi-threaded scaling: 8.4 GB/s single-thread -> 92 GB/s on 16 cores
blake3 = { version = "1", features = ["mmap", "rayon"] }

# Memory-mapped I/O - memmap2 for parallel hashing of large files
memmap2 = "0.9"

# Directory Walking - jwalk for parallel traversal (4x faster than walkdir)
# Provides sorted streaming results, rayon-powered parallelism
jwalk = "0.8"
# Keep walkdir as fallback for simpler single-threaded cases
walkdir = "2"

# Parallel Processing - Rayon is the de facto standard
# Work-stealing thread pool, near-linear scaling with cores
rayon = "1.10"

# Progress Bars - indicatif is mature and feature-rich
# 90M+ downloads, integrates with rayon, multi-bar support
indicatif = "0.17"

# Trash Support - Cross-platform recycle bin
# Windows: IFileOperation, macOS: NSFileManager, Linux: Freedesktop spec
# Note: Minor thread-safety caveat on Linux with mount operations
trash = "5"

# Human-Readable File Sizes - bytesize is lightweight and popular
# 3.3M downloads/month, supports SI (KB/MB) and IEC (KiB/MiB)
bytesize = "2"

# Ignore Patterns - gitignore-style pattern matching
# Same library used by ripgrep, handles .gitignore files natively
ignore = "0.4"

# Error Handling - anyhow for applications, thiserror for libraries
anyhow = "1"

# Database - rusqlite for persistent hash caching
# Using bundled feature for self-contained cross-platform builds

# Config/Cache Directory Discovery - XDG on Linux, AppData on Windows
directories = "5"

# System Information - sysinfo for detecting system resources (memory, disk type)
# Enables adaptive buffer sizing and optimized resource allocation

# Configuration File Parsing - TOML is the Rust ecosystem standard
# Used with figment for layered config (defaults < file < env < CLI)
toml = "0.8"

# Layered Configuration - figment enables hierarchical config merging
# Supports: defaults < config file < environment variables < CLI flags

# Perceptual Image Similarity - FC-005
# Disable default image features and explicitly enable needed formats
# JPEG uses zune-jpeg which has broken ARM64 NEON code in Rust 1.85
# See: https://github.com/etemesi254/zune-image/issues/343
