Struct template eps

Struct template eps_parser

boost::parser::eps_parser

Synopsis

// In header: <boost/parser/parser_fwd.hpp>

template<typename Predicate> 
struct eps_parser {
};

Description

Matches anything, and consumes no input. If Predicate is anything other than detail::nope (which it is by default), and pred_(ctx) evaluates to false, where ctx is the parser context, the parse fails.
