StrStyle does not implement common traits

[madsmtm]

It seems like syn::StrStyle does not implement the common traits Clone, Copy, Debug, PartialEq, Eq and Hash. Is this intentional, or an oversight?

StrStyle is vestigial as far as I can tell. It does not appear as a field in any syntax tree data structures, or in any public function signatures. Did you have a use case that benefits from using syn::StrStyle as opposed to your own enum?

Most likely we planned to add impl LitStr { pub fn style(&self) -> StrStyle } at some point but never found a use for it.

Nope, I don't actually use it, I just spotted it in passing.

Great!

I'll plan to delete StrStyle in the next version. #1566
