    def Lean.Elab.checkTerminationByHints (preDefs : Array PreDefinition) :
    CoreM Unit

    Checks consistency of a clique of TerminationHints:

    • If not all have a hint, the hints are ignored (log error)
    • None have both termination_by and partial_fixpoint (throw error)
    • If one has structural or partial_fixpoint, check that all have it (else throw error)
    • A structural should not have a decreasing_by (else log error)
