Hi Chrome Rust folks,

My team (the Google i18n team) is working on bringing ICU4X, a next gen i18n library in Rust, into Chromium and V8 via two avenues: one for experimenting with replacing usage of ICU4C transliterator, and one for implementing ECMAScript Temporal in V8.

We have obtained ATL approval here.

The plan for transliterator (and other components) is sketched out in go/icu4x-chromium-investigation and go/icu-in-chromium-usage-2024.

Temporal in V8 is planned in go/v8-icu402, tracked in b/401065166.

We are interested in other clients of the ICU4X library; please do reach out if you have interest in using ICU4X (either for fresh usage, or for replacing an ICU4C dependency.

Thanks,

-Manish

Thanks! We're happy to see additional experiments with using Rust libraries in Chromium. Let me cc @danno and @hpayer as an FYI, since I assume that somebody in their org will act as OWNERS for LGTM-ing v8 CLs once the project is ready for v8 integration.
