struct AST

A regex abstract syntax tree.

init(_ root: AST.Node, globalOptions: AST.GlobalMatchingOptionSequence?, diags: Diagnostics)

var captureList: CaptureList { get }

The capture list (including the whole match) of this AST.

var diags: Diagnostics

var globalOptions: AST.GlobalMatchingOptionSequence?

var hasCapture: Bool { get }

Whether this AST tree contains at least one capture nested inside of it.

var isInvalid: Bool { get }

Whether this AST tree is either syntactically or semantically invalid.

var root: AST.Node

@discardableResult func ensureValid() throws -> AST

If the AST is invalid, throws an error. Otherwise, returns self.
