I am just writing to see if Zeppelin had discontinued support for upgradable Libraries in Solidity or if not, whether they would even solve my use case
Right now, we would just love a sub-set of our contracts functionality to be isolated.
The functionality will ideally accept a
storage struct as an arg so we can access an internal mapping. A library seems like a perfect use case for this - however we would love for it to be upgradable. Past the blog post (https://medium.com/zeppelin-blog/proxy-libraries-in-solidity-79fbe4b970fd) in 2017… I can’t see anything from Zeppelin on this. Is it possible? Does it function just the same as a regular solidity lib? Would some special
delegateCall needed on the sending side to access storage, or is it even possible through a proxy contract?
