I’m trying to write a proc_macro that automatically implement a trait for a struct. The trait is as follows

trait StructName {
    fn name(&self) -> &'static str;
}

However, I found it hard to escape quote mark in the quote macro, for example, the following code is not working

let self_ty: Box<syn::Type> = ...;
quote!(
    impl StructName for #self_ty {
        fn name(&self) -> &'static str {
            "#self_ty"
        }
    }
)

How to escape quote mark in the quote macro?
