Is it possible for darling to support #[rename_all(serialize="snake_case", deserialize="camelCase")]

[pymongo]

serde support both #[rename_all="snake_case"] and #[rename_all(serialize="snake_case", deserialize="camelCase")]

here is my try: pymongo@edf5dc5

#[Derive(Object)]
#[rename_all(serialize="snake_case", deserialize="camelCase")]
struct A;

But I think darling is impossible to support:

#[derive(Debug, Copy, Clone, FromMeta)]
pub(crate) enum RenameAllRule {
    RenameRule(RenameRule),
    Serde {
        serialize: Option<RenameRule>,
        deserialize: Option<RenameRule>
    }
}

Yes, you need to implement FromMeta yourself, the FromMeta macro does not support this.
