Integers are for numbers, enabling arithmetic like subtractions and for loops without getting shot in the foot. Unsigneds are for bitfields. - "int" for numbers that will always be laughably smaller than four billion, and where we don't care about the serialization format. - "int32" for numbers that will always be laughably smaller than four billion, and will be serialized to four bytes. - "int64" for numbers that may approach four billion or will be serialized to eight bytes. - "uint32" and "uint64" for bitfields, depending on required number of bits and serialization format. Likewise "uint8" and "uint16", although rare in this project since they don't exist in XDR. - "int8", "int16" and plain "uint" are almost never useful.
