NAME
       std::__detail - Implementation details not part of the namespace std
       interface.


SYNOPSIS
   Classes
       struct _BracketMatcher
           Matches a character range (bracket expression).
       class _Compiler
           Builds an NFA from an input iterator range.
       class _Executor
           Takes a regex and an input string and does the matching.
       struct _List_node_base
           Common part of a node in the list.
       struct _List_node_header
           The list node header.
       struct _Quoted_string
           Struct for delimited strings.
       class _Scanner
           Scans an input range for regex tokens.
       class _StateSeq
           Describes a sequence of one or more _State, its current start and
           end(s). This structure contains fragments of an NFA during
           construction.
