Scalar Value Types

.proto Type Notes C++ Java
double
double double
float
float float
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 2^28. uint32 int
fixed64
Always eight bytes. More efficient than uint64 if values are often greater than 2^56. 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
