This is good, thank you!

Can you please fix the blocking issues?

Looks like the build is failing on:

              found enum `access_tier::AccessTier`

Were you able to build everything locally? Just guessing from the error above, it seems like it wants a Some(access_tier) instead of access_tier.

Ah, my branch is behind. Rebased and rebuilt and it's fine now.
