Function verify_and_copy_files 

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

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

Examples

use ssg::verify_and_copy_files;
use tempfile::tempdir;
use std::fs;

let src_dir = tempdir().unwrap();
let dst_dir = tempdir().unwrap();
fs::write(src_dir.path().join("a.txt"), "data").unwrap();
verify_and_copy_files(src_dir.path(), dst_dir.path()).unwrap();
assert!(dst_dir.path().join("a.txt").exists());

Security

This function implements several security measures:

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