Documentation
data EvaluationContext Source #
An opaque type that contains all the static parameters that the evaluator needs to evaluate a script. This is so that they can be computed once and cached, rather than recomputed on every evaluation.
There are two sets of parameters: one is with immediate unlifting and the other one is with deferred unlifting. We have to keep both of them, because depending on the language version either one has to be used or the other. We also compile them separately due to all the inlining and optimization that need to happen for things to be efficient.

mkEvaluationContext :: (MonadError CostModelApplyError m, MonadWriter [CostModelApplyWarn] m) => [Integer] -> m EvaluationContext Source #
Build the EvaluationContext.
The input is a list of integer values passed from the ledger and are expected to appear in correct order.
assertWellFormedCostModelParams :: MonadError CostModelApplyError m => CostModelParams -> m () Source #
Comparably expensive to mkEvaluationContext, so it should only be used sparingly.
data CostModelApplyError Source #
The type of errors that applyParams can throw.
