func diagnose(_ diagnostic: Diagnostic) Produce a diagnostic while expanding the macro.
func location(of node: some SyntaxProtocol, at position: PositionInSyntaxNode, filePathMode: SourceLocationFilePathMode) -> AbstractSourceLocation? Retrieve a source location for the given syntax node.
func makeUniqueName(_ name: String) -> TokenSyntax Generate a unique name for use in the macro.
func addDiagnostics(from error: Error, node: some SyntaxProtocol) Adds diagnostics from the error thrown during a macro expansion.
