unexpected nodes or
tokens with a TokenDiagnostic of severity error
import SwiftSyntaxA library for working with Swift code.
protocol RawSyntaxNodeProtocol : CustomStringConvertible, Sendable, TextOutputStreamableAll typed raw syntax nodes conform to this protocol. RawXXXSyntax is a typed wrappeer of RawSyntax.
@frozen struct BoolA value type whose instances are either true or false.
struct TokenDiagnosticIf the token has an error that’s inherent to the token itself and not its surrounding structure, this defines the type of the error. byteOffset specifies at which offset the error occurred.
var description: String { get }var isEmpty: Bool { get }func `as`<Node>(_: Node.Type) -> Node? where Node : RawSyntaxNodeProtocol Cast to the specified raw syntax type if possible.
func cast<S>(_ syntaxType: S.Type) -> S where S : RawSyntaxNodeProtocol func `is`<Node>(_: Node.Type) -> Bool where Node : RawSyntaxNodeProtocol Check if this instance can be cast to the specified syntax type.
