Error type for feed()

Variants

InvalidNonTerminal(&'a NonTerm, &'a [ProductionRule<Term, NonTerm>], &'a [State<Term, NonTerm>], Vec<usize>)

Invalid non-terminal feeded. This must not occur if the grammar is correct

InvalidTerminal(Term, &'a [ProductionRule<Term, NonTerm>], &'a [State<Term, NonTerm>], Vec<usize>)

Invalid terminal feeded

Callback(CallbackError)

Error from callback trait

ReduceAction(ReduceActionError)

Error from macro reduce action
