Documentation

data CostModel machinecosts builtincosts Source #

We need to account for the costs of evaluator steps and also built-in function evaluation. The models for these have different structures and are used in different parts of the code, so inside the valuator we pass separate objects about most of the time . It's convenient for clients of the evaluator to only have to worry about a single object, so the CostModel type bundles the two together. We could conceivably have different evaluators with different internal costs, so we keep the machine costs abstract. The model for Cek machine steps is in UntypedPlutusCore.Evaluation.Machine.Cek.CekMachineCosts.

data MachineParameters machinecosts term (uni :: Type -> Type) (fun :: Type) Source #

At execution time we need a BuiltinsRuntime object which includes both the cost model for builtins and their denotations. This bundles one of those together with the cost model for evaluator steps. The term type will be CekValue when we're using this with the CEK machine.

MachineParameters

toMachineParameters :: (UniOf (val uni fun) ~ uni, CostingPart uni fun ~ builtincosts, HasConstant (val uni fun), ToBuiltinMeaning uni fun) => CostModel machinecosts builtincosts -> MachineParameters machinecosts val uni fun Source #

This just uses toBuiltinsRuntime function to convert a BuiltinCostModel to a BuiltinsRuntime.
