What's the correct opEquals signature for structs?

Thank you for your answers, now I understand.
Using an int makes sense for opEquals, because if opEquals doesn't get inlined then using int is sometimes able to give you a bit more efficiency (there is no need to convert values different from 0 and 1 to 1). I don't know how much this saves you on modern CPUs (probably no more than few CPU cycles).
