Event signature when the event has an enum type

[atiselsts]

What's the correct way how to use cast sig-event to get signature of an event with an enum parameter?

Taking the source code literally gives an incorrect result, for example:

$ cast sig-event "ValidatorSlashed(address indexed operatorAddress, uint256 jailUntil, uint256 slashAmount, SlashType slashType)"
0x99e8d5654c23e7b98f71248ec5fe96b39cb54a22ef947f1906070f825ed9a48b

Replacing the enum argument with uint8 fixes the problem. This signature matches web3.py output from the contract's ABI:

$ cast sig-event "ValidatorSlashed(address indexed operatorAddress, uint256 jailUntil, uint256 slashAmount, uint8 slashType)"
0x6e9a2ee7aee95665e3a774a212eb11441b217e3e4656ab9563793094689aabb2

But is it always guaranteed to be uint8?
