int32 Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead. int32 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
|
|||
|
uint32 Uses variable-length encoding. uint32 int
|
|||
|
uint64 Uses variable-length encoding. uint64 long
|
|||
|
sint32 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. int32 int
|
|||
|
sint64 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s. int64 long
|
|||
|
fixed32 Always four bytes. More efficient than uint32 if values are often greater than 228. uint32 int
|
|||
|
fixed64 Always eight bytes. More efficient than uint64 if values are often greater than 256. uint64 long
|
|||
|
sfixed32 Always four bytes. int32 int
|
|||
|
sfixed64 Always eight bytes. int64 long
|

bool bool boolean
|

|
string A string must always contain UTF-8 encoded or 7-bit ASCII text. string String
|
|||
|
bytes May contain any arbitrary sequence of bytes. string ByteString
