copy

Efficiently copies entire directory trees while preserving structure, as shown in the basic Copy function that handles all subdirectories automatically.

Offers a comprehensive Options struct with callbacks for symlinks, errors, and file skipping, allowing developers to tailor behavior to complex edge cases.

Supports configurable worker counts via NumOfWorkers for faster copying of large directories, leveraging Go's goroutines for scalability.

Works with any fs.FS implementation, including embedded filesystems like embed.FS, enabling versatile use beyond the OS filesystem.

Provides OnError callbacks for custom error handling and recovery, as detailed in the Options, making it robust for production environments.
