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

    Checks consistency of a clique of TerminationHints:

    • If not all have a hint, the hints are ignored (log error)
    • If one has structural, check that all have it, (else throw error)
    • A structural should not have a decreasing_by (else log error)
    Equations
    • One or more equations did not get rendered due to their size.
