Make fields public for syn::Visibility

[StackOverflowExcept1on]

for example I want to make the visibility of each field public but the creation of syn::Visibility::Public(_) is not allowed

for field in fields.named.iter_mut() {
    field.vis = syn::Visibility::Public(syn::Token![pub]);
}

   --> utils/weight-diff/src/main.rs:251:33
    |
251 |                     field.vis = syn::Visibility::Public;
    |                     ---------   ^^^^^^^^^^^^^^^^^^^^^^^ expected `Visibility`, found enum constructor

instead you need to do it like this:

field.vis = syn::parse2(quote! { pub }).unwrap();

The code you wrote works, and is different from the code in the error message you pasted. I think this is most likely a case of you confusing yourself with 2 different copies of your own code, but if not, please take your questions to any of the resources shown in https://www.rust-lang.org/community and someone should be able to help you figure things out.
