To ease use of rkv in Firefox/Gecko, we should expose an XPCOM FFI to it.

What's RKV?

rkv is a Rust interface to the LMDB key-value storage engine. We vendored it into mozilla-central in bug 1445451, and we're investigating its use to replace a variety of the bespoke engines and formats for persisting data in Firefox (as documented in https://github.com/mozilla/firefox-data-store-docs).

Hey Myk, this has r+, should it land or is it waiting on other work?

(In reply to Jared Wein [:jaws] (Regression Engineering Owner for 65) (please needinfo? me) from comment #5) > Hey Myk, this has r+, should it land or is it waiting on other work? Good question! Lina reviewed parts of the revision and gave r+, but this is still awaiting review of the rest of the revision from Nika, who is the overall (blocking) reviewer for the changes; so this isn't quite ready to land yet. I'm not quite how best to represent that in this bug. Perhaps the simplest solution would be to remove the review+ flag on the attachment, since the Phabricator revision <https://phabricator.services.mozilla.com/D6328> is the source of truth for review status. If I remember correctly, we recently updated our Phabricator installation to no longer set Bugzilla review flags in part because they can be misleading, as they are in this case.
