Have you tested your changes locally? Looks like it produces incorrect code for some test cases (hence the CI failures).

sorry,I realized that the quote in the multiple_output branch includes a comma.

self.graph_output_types.iter().for_each(|output| {
let name = output.name();
let ty = output.ty();
if multiple_output {
output_type_def.extend(quote! {
#ty,
});
output_return_def.extend(quote! {
#name,
});
} else {
output_type_def.extend(quote! {
#ty
});
output_return_def.extend(quote! {
#name
});
}
});
