The semantics of this variant are unclear: sometimes a timeline could be cleared, which would result in a `UpdateTimeline` (and if we looked at the vector diffs, it would include a `Clear`), but in this case the `Clear` variant would not be emitted. It was only emitted in a few adhoc spots, but it was missing the whole picture. Also, the current observer was only interested in getting *a* room update with the room id, and didn't react particularly to clears. So, there's apparently little reason in having this variant, and as a result we should get rid of it.
Matrix Rust SDK
The Matrix Rust SDK is a collection of libraries that make it easier to build Matrix clients in Rust.
Development of the SDK is proudly sponsored and maintained by Element. Element uses the SDK in their next-generation mobile apps Element X on iOS and Android and has plans to introduce it to the web and desktop clients as well.
The SDK is also the basis for multiple Matrix projects and we welcome contributions from all.
Purpose
The SDK takes care of the low-level details like encryption, syncing, and room state, so you can focus on your app's logic and UI. Whether you're writing a small bot, a desktop client, or something in between, the SDK is designed to be flexible, async-friendly, and ready to use out of the box.
Project structure
The Matrix Rust SDK is made up of several crates that build on top of each other. The following crates are expected to be usable as direct dependencies:
- matrix-sdk-ui – A high-level client library that makes it easy to build full-featured UI clients with minimal setup. Check out our reference client, multiverse, for an example.
- matrix-sdk – A mid-level client library, ideal for building bots, custom clients, or higher-level abstractions. You can find example usage in the examples directory.
- matrix-sdk-crypto – A standalone encryption state machine with no network I/O, providing end-to-end encryption support for Matrix clients and libraries. See the crypto tutorial for a step-by-step introduction.
All other crates are effectively internal-only and only structured as crates for organizational purposes and to improve compilation times. Direct usage of them is discouraged.
Status
The library is considered production ready and backs multiple client implementations such as Element X [1] [2], Fractal and iamb. Client developers should feel confident to build upon it.
Bindings
The higher-level crates of the Matrix Rust SDK can be embedded in other environments such as Swift, Kotlin, JavaScript, and Node.js. Check out the bindings/ directory to learn more about how to integrate the SDK into your language of choice.
