PlutusCore.Evaluation.Result

Description

This module defines a common type various evaluation machine use to return their results.

Synopsis

class AsEvaluationFailure err where
- _EvaluationFailure :: Prism' err ()
evaluationFailure :: AsEvaluationFailure err => err
_EvaluationFailureVia :: Eq err => err -> Prism' err ()
data EvaluationResult a
- = EvaluationSuccess a
- | EvaluationFailure
isEvaluationSuccess :: EvaluationResult a -> Bool
isEvaluationFailure :: EvaluationResult a -> Bool

Documentation

evaluationFailure :: AsEvaluationFailure err => err Source #

_EvaluationFailureVia :: Eq err => err -> Prism' err () Source #

Construct a Prism focusing on the *EvaluationFailure part of err by taking that *EvaluationFailure and

returning it for the setter part of the prism
checking the error for equality with *EvaluationFailure for the opposite direction.

data EvaluationResult a Source #

The parameterized type of results various evaluation engines return. On the PLC side this becomes (via makeKnown) either a call to Error or a value of the PLC counterpart of type a.
