Compiler config to disable generation of new method #23

Closed dudycz closed 1 month ago

dudycz commented 3 months ago

Hello,

In case of complex and big ASN1 definitions (like the ones from 3gpp) generated new() methods are causing clippy warnings: "this function has too many arguments" Having an option to choose whether to generate new or not would solve this kind of issue.

Thank you for your issue. The generated new constructors are provided to create instances of non_exhaustive structs, as these cannot be constructed with a StructExpression. If we don't want to plainly ignore the clippy warning in the generated bindings, we would need to generate another way of constructing non_exhaustive types, for example a builder. To be honest, I would simply #![allow(clippy::too_many_arguments)], but if you feel motivated to implement a more elegant solution I'd be more than happy to review it.

Do you mean to add #![allow(clippy::too_many_arguments)] in the generated module, right? It would be great and solve this problem.

6d7a commented 3 months ago

Yes, it's merely a matter of adding too_many_arguments to the allowed lints here.

I believe this could be closed with #29, not sure why it did not auto-close.
