Struct concorde::Opinion

pub struct Opinion<ObjLD: LatticeDef, Peer: DefTraits> {
    pub estimated_commit: StateLE<ObjLD, Peer>,
    pub proposed_configs: ArcOrdSet<CfgLE<Peer>>,
    pub candidate_object: LatticeElt<ObjLD>,
}

Participants store, exchange and update Opinions about the values in the Cfg and Obj lattices as they attempt to come to an agreement.

The term Opinion does not appear in the paper, but I've introduced it (along with the field names in it) in an attempt to clarify the presentation and bundle-together the 3 variables that are used as a group in both local state and message bodies.

Fields

estimated_commit: StateLE<ObjLD, Peer>

called vₚ in the paper

proposed_configs: ArcOrdSet<CfgLE<Peer>>

called Tₚ in the paper

candidate_object: LatticeElt<ObjLD>

called objₚ in the paper
