For each recipient device, we keep an "Olm wedging index" that indicates (approximately) how many times they tried to unwedge the Olm session. When we share a Megolm session, we store the Olm wedging index. This allows us to tell whether the Olm session was unwedged since we shared the Megolm session, so that we know if we should re-share it. We detect an attempt to unwedge the Olm session by checking if the Olm message that we decrypted is from a brand new Olm session. This is not entirely accurate, since this could happen, for example, if Alice and Bob create Olm sessions at the same time. This may result in some Megolm sessions being re-shared unnecessarily, but should not make a huge difference.
matrix-rust-sdk
matrix-rust-sdk is an implementation of a Matrix client-server library in Rust.
Project structure
The rust-sdk consists of multiple crates that can be picked at your convenience:
- matrix-sdk - High level client library, with batteries included, you're most likely interested in this.
- matrix-sdk-base - No (network) IO client state machine that can be used to embed a Matrix client in your project or build a full fledged network enabled client lib on top of it.
- matrix-sdk-crypto - No (network) IO encryption state machine that can be used to add Matrix E2EE support to your client or client library.
Minimum Supported Rust Version (MSRV)
These crates are built with the Rust language version 2021 and require a minimum compiler version of 1.70.
Status
The library is in an alpha state, things that are implemented generally work but the API will change in breaking ways.
If you are interested in using the matrix-sdk now is the time to try it out and provide feedback.
Bindings
Some crates of the matrix-rust-sdk can be embedded inside other
environments, like Swift, Kotlin, JavaScript, Node.js etc. Please,
explore the bindings/ directory to learn more.
