The Rust font stack for Chrome integrates the Fontations font libraries into Chromium as a safe replacement for FreeType (https://github.com/googlefonts/fontations/). This project is a collaboration between Chrome and Google Fonts. By replacing FreeType we make font processing in Chrome safer and more reliable and move from a C codebase to a modern set of efficient and ergonomic Rust libraries for font processing in Chrome. We reduce the engineering time needed to keep FreeType secure and spend less time having to address incoming issues found by Fuzzers. We open up the possibility of unsandboxing font processing code. We move to relying on a shared codebase for font processing in Chrome and font production in Google Fonts. Internal document: http://go/rust-fontstack-chrome
