implement `Copy` for `Nothing` #1596

Closed programmerjake closed 7 months ago

programmerjake commented 7 months ago

I have a generic struct MyAttr<Body> that I use to hold a parsed #[my_attr(<body>)], I want to use MyAttr<Nothing>: Clone where I want to hold a parsed #[my_attr], but Nothing doesn't implement Clone.

I see no reason why it can't just implement Copy.

related, it would also be nice to implement ToTokens
