Problem
The removal of the
Copy
derivation onRent
andEpochSchedule
in solana-labs#32767 is a breaking change, and wasn't signaled to downstream users who were depending on theCopy
behavior, such as https://discord.com/channels/428295358100013066/966782389839876096/1250593405118058616Summary of Changes
The breaking change is fine for 2.0, but we should at least re-establish the Copy derivation for 1.18 to avoid unnecessary downstream breakage.
I should have realized this while reviewing the SPL PRs but didn't think it would impact anyone (wrongly).
Note that this PR doesn't revert the previous PR, but simply re-adds the
Copy
derivation and adds a few#[allow(...)]
s for clippy to pass, so there's no change in behavior.Fixes #
