need_more = 1

== Description


A rule reached the end of the input,
resulting in a partial match. The error
is recoverable; the caller may obtain
more input if possible and attempt to
parse the character buffer again.
Custom rules should only return this
error if it is completely unambiguous
that the rule cannot be matched without
more input.
