A wrapper for parsers that provides the operations that must be supported by all parsers (e.g. operator>>()
). GlobalState
is an optional state object that can be accessed within semantic actions via a call to _globals()
. This global state object is ignored for all but the topmost parser; the topmost global state object is available in the semantic actions of all nested parsers. ErrorHandler
is the type of the error handler to be used on parse failure. This handler is ignored on all but the topmost parser; the topmost parser's error handler is used for all errors encountered during parsing.

constexpr auto () ;
Returns a parser_interface
containing a parser equivalent to an expect_parser
containing parser_
, with FailOnMatch == true
.

containing a parser equivalent to a zero_plus_parser
containing parser_

template<typename ParserType2> constexpr auto (parser_interface< ParserType2 > rhs) ;
Returns a parser_interface
containing a parser equivalent to a seq_parser
containing parser_
followed by rhs.parser_
.
constexpr auto (char rhs) ;

template<typename ParserType2> constexpr auto (parser_interface< ParserType2 > rhs) ;
Returns a parser_interface
containing a parser equivalent to a seq_parser
containing parser_
followed by rhs.parser_
. No back-tracking is allowed after parser_
succeeds; if rhs.parser_
fails after parser_
succeeds, the top-level parse fails.
constexpr auto (char rhs) ;
Returns a parser_interface
containing a parser equivalent to a seq_parser
containing parser_
followed by lit(rhs)
. No back-tracking is allowed after parser_
succeeds; if lit(rhs)
fails after parser_
succeeds, the top-level parse fails.
constexpr auto (char32_t rhs) ;
Returns a parser_interface
containing a parser equivalent to a seq_parser
containing parser_
followed by lit(rhs)
. No back-tracking is allowed after parser_
succeeds; if lit(rhs)
fails after parser_
succeeds, the top-level parse fails.
template< R> constexpr auto (R && r) ;
Returns a parser_interface
containing a parser equivalent to a seq_parser
containing parser_
followed by lit(rhs)
. No back-tracking is allowed after parser_
succeeds; if lit(rhs)
fails after parser_
succeeds, the top-level parse fails.
template<typename ParserType2> constexpr auto (parser_interface< ParserType2 > rhs) ;
Returns a parser_interface

containing parser_

.
template<typename ParserType2> constexpr auto (parser_interface< ParserType2 > rhs) ;
Returns a parser_interface
containing a parser equivalent to a perm_parser
containing parser_
followed by rhs.parser_
. It is an error to use eps
(conditional or not) with this operator.
constexpr auto (char rhs) ;
Returns a parser_interface
containing a parser equivalent to an or_parser
containing parser_
followed by lit(rhs)
.
constexpr auto (char32_t rhs) ;

template<typename ParserType2> constexpr auto (parser_interface< ParserType2 > rhs) ;
Returns a parser_interface

template< R> constexpr auto (R && r) ;
Returns a parser_interface
containing a parser equivalent to an delimited_seq_parser
containing parser_

.
template<typename Action> constexpr auto (Action action) ;
Returns a parser_interface
containing a parser equivalent to an action_parser
containing parser_
, with semantic action action
.
template<typename Arg, Args> constexpr auto (Arg && arg, Args &&... args) ;
Returns parser_((Arg &&)arg, (Args &&)args...)
. This is useful for those parsers that have operator()
overloads, e.g. <lsquo></lsquo>char_('x<rsquo></rsquo>)<lsquo></lsquo>. By convention, parsers<rsquo></rsquo> operator()
s return parser_interface
s.
This function does not participate in overload resolution unless parser_((Arg &&)arg, (Args &&)args...)
is well-formed.
