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.
