Show HN: DriveSync – fast Git-styled Google Drive sync CLI

DriveSync is a Rust-based CLI that synchronizes a local directory with a Google Drive folder, supporting push, pull, and diff operations and honoring .driveignore patterns. It authenticates via an OAuth client created in Google Cloud Console, stores tokens locally, and uses size and MD5 checks to minimize data transfer. Installable via Homebrew, prebuilt binaries, or source compilation, it runs on macOS, Linux and Windows with documented limitations.
