import _RegexParser

struct AbsentFunction

An Oniguruma absent function.

struct AST

A regex abstract syntax tree.

case clearer

An absent clearer (?~|) which cancels the effect of an absent stopper.

case expression(absentee: AST.Node, pipe: SourceLocation, expr: AST.Node)

An absent expression (?~|absent|expr), which defines an absent pattern which must not be matched against while the pattern expr is matched.

case repeater(AST.Node)

An absent repeater (?~absent). This is equivalent to (?~|absent|.*) and therefore matches as long as the pattern absent is not matched.

case stopper(AST.Node)

An absent stopper (?~|absent), which prevents matching against absent until the end of the regex, or until it is cleared.

init(_ kind: AST.AbsentFunction.Kind, start: SourceLocation, location: SourceLocation)

var children: [AST.Node] { get }

var kind: AST.AbsentFunction.Kind

var location: SourceLocation

var start: SourceLocation

The location of (?~ or (?~|

enum Start

protocol Equatable

A type that can be compared for value equality.

protocol Hashable : Equatable

A type that can be hashed into a Hasher to produce an integer hash value.
