std::__detail(3cxx)

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.
