I think that crown currently goes to https://github.com/googlefonts/fontations which is included in Chromium, not sure if it's on all platforms yet. Moreover, the translative dependencies of Fontations (click through https://crates.io/crates/fontations/0.3.0/dependencies) should have an even (slightly) larger install-base.
EDIT: from the quote you can also gather that they don't use https://github.com/signalapp/libsignal
Just a few more Rust libraries we've shipped in Chromium:

- https://github.com/webmproject/CrabbyAvif
- https://github.com/RCasatta/qr_code
