Note: Linux and Windows tests run in Google Cloud VMs to ensure the correct file system is used. MacOS tests run only GitHub Actions.
Description
This project is an implementation of Copy-On-Write (CoW) or reflinks in Rust. It provides file copy functionalities that are optimized for different file systems and operating systems.
Features
- Unix/MacOS: Uses the
reflink-copycrate for CoW support. - Windows: Native implementation supporting ReFS drives (Windows Server 2016+ and Windows 11 Dev Drives).
Usage Demo
Here's a simple demo showing how to use this library.
use copy_on_write::reflink_file_sync;
reflink_file_sync(src, dst);
