Submission Details
Severity:
`HorseStore.huff` doesn't implement all the functionality of `HorseStore.sol`, causing both contracts not to be equivalent
Description
According to the documentation:
Every function in the solidity rendition has been re-written in huff
However this is not the case. Important inherited functions in HorseStore.sol are missing in HorseStore.huff
For example ERC721Enumerable.sol::tokenOfOwnerByIndex has no equivalent in HorseStore.huff.
Impact
HorseStore.sol and HorseStore.huff cannot be considered equivalent, contradicting the documentation.
HorseStore.huff does not provide the required functionality.
Proof of concept
No tokenOfOwnerByIndex function defined in HorseStore.huff::MAIN.
Recommended mitigation
Implement the missing features in HorseStore.huff.
