Struct RequestId 

pub struct RequestId(pub u64);

A request’s identifier, chosen by the client that sent it.

A transport correlation token: the node echoes it on the request’s final reply frame and keeps no state about it, so it is never checked for uniqueness or order, and 0 is as valid as any other value. It means nothing outside its connection’s lifetime, and is never journaled, replicated, or handed to the application.

A newtype so it cannot be swapped with the connection ID it travels beside. u64 so a connection that lives for months at millions of requests a second never has to ask what happens when it wraps.
