Struct Hop 

pub struct Hop<'a> {
    pub engines: Vec<&'a Engine>,
    pub transport: TpTransport,
    pub link: Option<&'a PeerPullLink>,
}

Everything a hop needs: the rank engines (index = rank, [0] = root), the transport arm, and (on the peer-pull arm) the publication link. Built by the caller per hop from the TP runtime, so this module never has to own the runtime type and the borrow shapes at the call sites stay exactly as they are today.

Fields

engines: Vec<&'a Engine>

transport: TpTransport

link: Option<&'a PeerPullLink>
