Font Awesome

Font Awesome is a company that makes icons for websites and applications. During my internship I helped bug fix their custom icon maker.

Icon Tester



My biggest contribution was the Icon Wizard Tester. It took Font Awesomes collection of icons and did boolean operations on them using Flo_Curves (The open source Rust crate Font Awesome uses for their icon maker). It then does the same operations using Google's Skia crate and finds differences. Any differences are bugs.


Rust



To make the Icon Wizard Tester I first had to learn Rust. This was the first month of my internship. I had to learn how to use the Borrow Checker, multithreading, and functional programming as well.

Flo_Curves



The Icon Wizard Tester found hundreds of possible bugs in Flo_Curves. I had time to make a minimal test case for one of them, and then sent it to the Flo_Curves developer who promptly fixed it.
