Slint structured file viewer with DuckDB

[cbritton]

My first app with slint! This is a simple structured file viewer (table view) using DuckDB as the engine to query the data files. Currently, this supports CSV and parquet although there's community support for lots more. The backend for this app is rust.

I pulled a lot of concepts together and tried to keep this simple so any newcomer to slint can benefit. I was pleasantly surprised how well the threading works with tokio.

Some ideas I wanted to adhere to:

• Global state to keep context centralized
• Tried to keep the slint files as clean as possible and easy to follow
• Updating the table UI via callback with tokio. While duckdb is busy getting data in the thread, the UI shows an active progress indicator
• In addition to column header names, include the data type
• Keep memory usage low by using pagination. In release mode, on my machine, this can easily handle a parquet file with 6 million rows.
