Cf_parser.cursor
The initial position, i.e. usually zeromethod error : int ->
('a * (< advance : 'a -> 'c; error : 'b; position : int; .. > as 'c))
Cf_seq.t -> unit as 'b
c#error n z
in a DFA when no rule
matches the input stream z
after n
symbols. The purpose is to
give a derived class an opportunity to raise an exception rather
that allow the parser to return without a match.
