Porting Librsvg Filters to Rust
The project
Librsvg is a small library for rendering SVG files in the GNOME ecosystem. Currently all filter effects in librsvg are implemented entirely in C. Additionally, most of them aren’t covered by specification conformance tests. I’m going to be porting the filter infrastructure to Rust, adding all missing tests and making sure everything works correctly.

About me
I’m Ivan Molodetskikh, a student of the Computational Mathematics and Cybernetics department of the Moscow State University. I’ll be blogging about this project over here.
You can ping me (YaLTeR) in the IRC where you can find me in #rust.
