throwingWithCause :: forall exc e t term m x. (exc ~ ErrorWithCause e term, MonadError exc m) => AReview e t -> t -> Maybe term -> m x Source #

Prismatically throw an error and its (optional) cause.

throwingWithCause_ :: forall exc e term m x. (exc ~ ErrorWithCause e term, MonadError exc m) => AReview e () -> Maybe term -> m x Source #

Prismatically throw a contentless error and its (optional) cause. throwingWithCause_ is to throwingWithCause as throwing_ is to throwing.

throwBuiltinErrorWithCause :: (MonadError (ErrorWithCause err cause) m, AsUnliftingEvaluationError err, AsEvaluationFailure err) => cause -> BuiltinError -> m void Source #

Attach a cause to a BuiltinError and throw that. Note that an evaluator might require the cause to be computed lazily for best performance on the happy path, hence this function must not force its first argument. TODO: wrap cause in Lazy once we have it.
