This will need facebook/rocksdb#12537

std::ptr::from_ref (1.76) slightly exceeds the MSRV (1.75). Would you like me to downgrade that or are you interested in bumping?

sorry, missed the notification for this for some reason, initially I wanted to stay with the latest, however, it looks like this is not recommended as it may cause issues for users of this crate. I'll likely adopt a similar policy to tokio. So let's not try to upgrade the MSRV for now.

Do you know any specific users you'd like to reach out to for permission to bump the MSRV in your fork of rust-rocksdb? conduwuit would really like this feature, our MSRV is already the latest.

would really like this feature

sorry, maybe i'm misunderstanding, the std::ptr::from_ref requires the new version, but you don't care about this part right? You can do it a different way (based on the comment Would you like me to downgrade that) and still get this pr/feature merged

[girlbossceo]

Yes just using an as conversion is fine, but I'm just wondering if an exception for a MSRV raise could be done here. If not, that's fine and you're right this feature will still land either way.

we can bump the MSRV one more time before we restrict it to the 6 month rolling releases.
