SolverTypes.GenericEqIncrSolverAn incremental solver takes the argument about postsolving.
module Arg : IncrSolverArgmodule S : ConstrSys.EqConstrSysmodule H : Batteries.Hashtbl.S with type key = S.vThe hash-map that is the first component of solve xs vs is a local solution for interesting variables vs, reached from starting values xs. As a second component the solver returns data structures for incremental serialization.
