Hello.
I have (working on) Rust service and clients ( Rust and Node.js). I want
service<->client cap'n'proto message exchange via Tcp socket (no HTTP).
Messages will go via tcp connection, but I have different message types
(each message is structs Login, or CommandGetData or Error...). So how can
I distinguish which message Type I got from tcp bytes stream (and I need to
know it's size too).
I decided to prefix each message with UInt32 type and size (8 bytes total).
Probably JS can read raw bytes. Or I can prefix Messages with fixed size
unpacked message (struct - 24 bytes).
struct MessageHeader {
type @0: UInt32;
size @1: UInt32;
}
So what is good solution for this task? I think it was already solved many
times. I understand, that RPC will solve this as JSON messages. But I do
not want use RPC right now.
