Module file 

Secure file operation utilities

This module provides safe file operations that protect against common security issues like symlink attacks and hard link manipulation.

Security Features

• Symlink attack prevention
• Hard link detection
• Path validation
• Safe file creation and opening

Example

use atlas_common::file::{safe_create_file, safe_open_file};
use std::io::{Read, Write};
use std::path::Path;

// Safely create a file
let mut file = safe_create_file(Path::new("output.txt"), false)?;
file.write_all(b"secure data")?;

// Safely read a file
let mut file = safe_open_file(Path::new("input.txt"), false)?;
let mut contents = String::new();
file.read_to_string(&mut contents)?;
