struct Reference

struct AST

A regex abstract syntax tree.

case named(String)

case relative(AST.Atom.Number)

init(_ kind: AST.Reference.Kind, recursionLevel: AST.Atom.Number? = nil, innerLoc: SourceLocation)

var innerLoc: SourceLocation

The location of the inner numeric or textual reference, e.g the location of ‘-2’ in ‘\g{-2}’. Note this includes the recursion level for e.g ‘\k<a+2>’.

var kind: AST.Reference.Kind

var recursesWholePattern: Bool { get }

Whether this is a reference that recurses the whole pattern, rather than a group.

var recursionLevel: AST.Atom.Number?

An additional specifier supported by Oniguruma that specifies what recursion level the group being referenced belongs to.

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.

var recursesWholePattern: Bool { get }

Whether this is a reference that recurses the whole pattern, rather than a group.

static func != (lhs: Self, rhs: Self) -> Bool

Returns a Boolean value indicating whether two values are not equal.
