real::regex_set::fused_state Struct Reference

The fused scan's state: the DFA, its subset maps, and what the deferred build counts. More...

Public Attributes
std::optional< dfa >	fused
	The fused DFA; empty until built, or when it cannot be.
std::vector< std::size_t >	eligible_orig
	fused rule k → construction index.
std::vector< std::size_t >	ineligible_orig
	construction indices needing search.
bool	partitioned {}
	The partition ran at construction.
std::atomic< std::uint64_t >	walked {0}
	Whole-subject bytes matches walked, until ready.
std::atomic< bool >	ready {false}
	The fields above are final (the DFA built or given up).
std::once_flag	once
	The deferred build runs once.

Detailed Description

The fused scan's state: the DFA, its subset maps, and what the deferred build counts.

Shared by copies of the set, and written once: at construction, or by the one call that builds it under once; ready publishes it. Held by pointer because the atomics and the once flag can be neither copied nor moved, and a set must stay both.
