Deserialize something into HashMap<Cow<'a, str>, MyStruct<;'a>>

[mainrs]

I am not entirely sure if this makes even that much sends due to HashMap key boundaries. But I'd like to have my HashMap keys either borrowed or, if not possible, be owned.

But the following code does not work:

#[serde_as(as = "HashMap<BorrowCow, MyStruct<'a>>")]
pub entries: HashMap<Cow<'a, str>, MyStruct<'a>>,

Is this possible?

You are missing some key details in your question, so it is hard to answer. If you provide a small compilable example, that makes is much easier to see what is going on and, very importantly, shows the error messages you get.

I think you might have the problem from #202.
In that case, the correct attribute is #[serde_as(as = "HashMap<BorrowCow, _>")].
