pzn-sync: Lightweight Desktop App Development

`pzn-sync` was a lightweight, fast desktop application written in Rust. Using the `iced` toolkit, the application was light on memory and started up instantaneously. Expected to stay running in the background and to be as portable as possible, webviews (like Tauri and Electron) were not viable. The result was a small (5MB), portable (fully software rendered) and fast little app that could be easily distributed to users.

Rust: Completely written in Rust, distributed on Windows and macOS.

iced: The GUI toolkit of choice.

reqwest: Files synced to the server were sent as multipart forms, reqwest provided the most usable implementation of this.

notify: File-system watcher library.

light-ini: lightweight ini parser, as the application saved it's internal config in this format.

The first MVP was made in about a week, and iteration was done with close instruction from the client. Once complete, we had the final binary tested for compatibility and performance on various setups. When complete, a 3-week support window was provided after compensation was completed. The project remains closed source, thus most of the source code is largely unavailable.
