Doc Comments

So this is my code

    pub fn generate_variant_def(&self) -> Tokens<Rust> {
        let name = &self.name.to_case(Case::UpperCamel);
        let requirement = &self.requirement;
        let switch_variant_type = self.switch_variant_type.generate_variant_type();
        quote! {
            ///This switch variant requires a value #requirement in the compare_to field
            #<line>
            #name #switch_variant_type,
        }
    }

It generates

# [ doc = "This switch variant requires a value #requirement in the compare_to field" ]

 MyVariant {

 test: i32 ,

 } ,

Requirement is equal to "12"

I'm not following. Could you try and elaborate on what the issue is?

Variables don't seem to be replacing themselves inside quote when on a comment

Gotcha, so interpolation does indeed not work inside of rust-style comments because they are passed into the macros as literal strings (as you can see in how they are expanded).

The way you have to work around this is by formatting the comment yourself:

quote! {
    #(format!("/// This switch variant requires a value {requirement} in the compare_to field"))
    #<line>
    #name #switch_variant_type,
}

I've also opened #26 which will allow you to use format_args! directly once merged, all though it would fundamentally accomplish the same thing.

    #(format!("/// This switch variant requires a value {requirement} in the compare_to field"))

Cool it works!. Thank you
