recursive_copy 1.0.1

✨ Features

• Fully recursive copy of directories and files.
• Basic protection against symlink loops.
• Configurable recursion depth limit (max_depth).
• Optional overwrite, symlink following, and permission preservation.
• Efficient I/O with adjustable buffer size.
• Safe defaults for minimal risk operations.

🧱 Compatibility

• Supported platforms: Linux, *BSD systems, Solaris.
• Requirements: A POSIX-compliant filesystem interface.
• Not supported: Windows (by design).

This crate uses only the Rust standard library and POSIX APIs (via std::os::unix), ensuring consistent behavior across Unix environments.

⚙️ Example

use recursive_copy::{copy_recursive, CopyOptions};
use std::path::Path;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let src = Path::new("/home/user/docs");
    let dst = Path::new("/backup/docs_copy");

    let opts = CopyOptions::default();
    let summary = copy_recursive(src, dst, &opts)?;

    println!("Copied {} bytes with {} errors", summary.bytes_copied, summary.errors);
    Ok(())
}

🔐 Security & Safety

• Prevents infinite recursion via a symlink loop detector.
• Enforces a maximum directory depth.
• Avoids accidental overwrites unless explicitly allowed.
• Supports permission preservation using POSIX mode bits.

🧩 Philosophy

This project follows a minimalist design philosophy:

• No dependencies — relies solely on the Rust standard library.
• Stable behavior — safe for system utilities, backups, and embedded tools.
• Secure by default — cautious handling of links, files, and permissions.

🤝 Contributing

Contributions are welcome! However, the project’s core principles are minimalism, security, and stability.

Please note:

• New functionality should only be added behind optional feature flags.
• The default build must remain dependency-free and minimal.
• Focus on code clarity and POSIX compliance.
