Deserializing buffer Protocol Buffer
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
I'm trying to deserialize buffer from socket.
It is defined as C struct.
One member of struct is uint8[5].
I stuck how to express that with .proto file.
Original C struct of sender is at below.
typedef struct
uint32_t body_length;
uint8_t body_version;
uint8_t reserved[5];
My struct.proto trial is at below.
syntax = "proto3";
message message_t
uint32 body_version = 1;
uint8 body_version = 2; //uint8_t body_version;
bytes reserved = 3; //uint8 reservered[5];
I don't know how to express uint8 and 5 byte sized array.
There's no uint8 and fixed size bytes at proto3 spec.

protobuf indeed doesn't have fixed size arrays, and the fixed size integers don't include 5 bytes. So; your best option is probably bytes, and just make it always contain exactly 5 bytes.
Note: protobuf is not intended as a mechanism for parsing arbitrary protocols / payloads such as socket frames or raw C-style dumps. It is only intended for use with protobuf itself.
