Classes
class	real::compat::re2::Arg
	A type-erased destination for one captured submatch, built implicitly from a pointer to std::string, std::string_view, bool or an arithmetic type, or from nullptr to skip the group. A submatch that does not convert fails the whole match call. More...

Namespaces
namespace	real
	REAL's public API: real::regex, real::static_regex, real::flags and the match/iterator types built on them.
namespace	real::compat
	Drop-in replacements for <regex>, backed by REAL's linear-time engine where it can serve the pattern and by std::regex otherwise, never by a silent divergence.
namespace	real::compat::re2
	Drop-in replacement for RE2's API surface, on REAL's engine.

Detailed Description

real::compat::re2 — RE2::Arg, the type-erased submatch-parser cell.

As RE2's: a void* destination and a function-pointer parser, so the match functions take a variadic list of output pointers (&i, &s, …) without a virtual call or an allocation.
