int32 Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead. int32 int int int32 Fixnum or Bignum (as required) int integer int
int64 Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead. int64 long int/long[3] int64 Bignum long integer/string[5] Int64
uint32 Uses variable-length encoding. uint32 int[1] int/long[3] uint32 Fixnum or Bignum (as required) uint integer int
uint64 Uses variable-length encoding. uint64 long[1] int/long[3] uint64 Bignum ulong integer/string[5] Int64
sint32 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. int32 int int int32 Fixnum or Bignum (as required) int integer int
sint64 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s. int64 long int/long[3] int64 Bignum long integer/string[5] Int64
fixed32 Always four bytes. More efficient than uint32 if values are often greater than 228. uint32 int[1] int/long[3] uint32 Fixnum or Bignum (as required) uint integer int
fixed64 Always eight bytes. More efficient than uint64 if values are often greater than 256. uint64 long[1] int/long[3] uint64 Bignum ulong integer/string[5] Int64
