The changes overall lgtm, with minor nits for declaring things breaking for overly clear communication. The yarn.lock is also so massive it broke something, and I'm concerned there's a package manager mismatch somewhere: I've sent you a DM to try and figure this out OOB, though is not necessarily a blocker for this PR landing.

I seem to recall that these database names are in a constant somewhere? If so, we should use them.

alternatively, we should consider making them constants for reasons of reliability.

not really, tbh: they are defined in the rust-sdk here and here.

Given they are only used once, I'm unconvinced that a constant will help reliability.
The prefix does come from the js-sdk so I can factor that out to a constant.

or whatever jsdoc wants to say this.

alternatively, apparently @internal will exclude it from public types, despite being public itself.

Well, it's not exported explicitly, and it's only dynamically referenced, so it doesn't actually appear in the generated documentation.

I don't know how or why yarn did this, but it's not doing it any more.
This PR adds an option to `config.json` which will make the js-sdk use the rust crypto sdk, instead of the libolm implementation.
To use it, you need to add something like this to `config.json`:
```
"features": {
"feature_rust_crypto": true
},
```
We don't (yet) have any way to migrate a device between implementations, so the setting that was in use when you log in is persisted to the device; it is *visible* via the labs section but cannot currently be changed.
This is part of element-hq/element-web#21972, and enables the functionality added to the js-sdk in matrix-org/matrix-js-sdk#2969.

This PR introduces
MatrixClient.initRustCrypto, which is similar toinitCrypto, except that it will use the Rust crypto SDK instead of the old libolm-based implementation.This is very much not something you want to use in production code right now, because the integration with the rust sdk is extremely skeletal and almost everything crypto-related will raise an exception rather than doing anything useful.
It is, however, enough to demonstrate the loading of the wasmified rust sdk in element web, and a react sdk with light modifications can successfully log in and out.
Part of element-hq/element-web#21972.
