type family PredicateFailure 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.
