Function verify_and_copy_files 

pub fn verify_and_copy_files(src: &Path, dst: &Path) -> Result<()>

Validates and copies files from source to destination.

This function performs comprehensive safety checks before copying files, including path validation, symlink detection, and size limitations.

Arguments

• src - Source path to copy from
• dst - Destination path to copy to

Returns

Returns Ok(()) if the copy operation succeeds, or an error if:

• Source path is invalid or inaccessible
• Source contains symlinks (not allowed)
• Files exceed size limits (default: 10MB)
• Destination cannot be created or written to

Example

use std::path::Path;
use ssg::verify_and_copy_files;

fn main() -> anyhow::Result<()> {
    let source = Path::new("source_directory");
    let destination = Path::new("destination_directory");

    verify_and_copy_files(source, destination)?;
    println!("Files copied successfully");
    Ok(())
}

Security

This function implements several security measures:

• Path traversal prevention
• Symlink restriction
• File size limits
• Permission validation
