WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
There's been a couple of attempts to classify the remaining ones, but as you can see it required looking into hundreds or even thousands of errors and trying to find a root cause. Even after that, fixing them can be quite tricky.
A new implementation of the trait sovler. It was meant to be used by rustc, but that work is currently postponed.
The immediate blocker for merging them is that today rust-analyzer isn't an official part of rust-lang project, de-jure it's still some random GitHub repo matklad started a while ago, although de-facto it isn't. We are working on rectifying that, current ETA is early next year (we aimed for several weeks ago actually, but then https://github.com/rust-lang/team/pull/671 understandably delayed things).
