Description

Parses [first, last) using parser, skipping all input recognized by skip between the application of any two parsers, and returns whether the parse was successful. When a callback rule r is successful during the parse, one of two things happens: 1) if r has an attribute, callbacks(tag, x) will be called (where tag is decltype(r)::tag_type{}, and x is the attribute produced by r); or 2) if r has no attribute, callbacks(tag) will be called. Callbacks is expected to be an invocable with the correct overloads required to support all successful rule parses that might occur. If trace_mode == trace::on, a verbose trace of the parse will be streamed to std::cout.
