The Matrix software development kit (SDK) written in Rust has been used in many applications, including but not limited to: Fractal, iamb, the Element X mobile applications, and even some bits of Element Web! Better support for sliding sync, more robust cryptography, higher-level and more convenient primitives for writing clients, bindings for other non-rusty languages, support for OpenID Connect, and much more… In this presentation we'll talk about what has happened in the Rust SDK last year, and what we'd like to see this incoming year.
