type family PredicateFailure a = (b :: Type) | b -> a Source #
Descriptive type for the possible failures which might cause a transition to fail.
As a convention, PredicateFailure
s which are "structural" (meaning that
they are not "throwable" in practice, and are used to pass control from
one transition rule to another) are prefixed with S_
.
Structural PredicateFailure
s represent conditions between rules where
the disjunction of all rules' preconditions is equal to True
. That is,
either one rule will throw a structural PredicateFailure
and the other
will succeed, or vice-versa.
