Iterator serialization support

[jprochazk]

This would offer greater flexibilty for serializing any array-like construct. For example, it would remove the need for intermediate allocations when transforming data before serializing it.

Unfortunately I don't think Rust coherence rules will allow that for QueryArg. But we may implement a derive with a flag, something like this:

#[derive(QueryArgs)]
struct MyArgs<'a> {
  #[query_arg(array_like)]
  queued_items: &'a Queue<String>,
}

Hello, by the way, do you have an example for

use edgedb_protocol::query_arg::QueryArgs;

#[derive(QueryArgs)]
struct MusicInput {
    pub artist: String
}

cannot find derive macro QueryArgs in this scope
Or do I have to implement it myself ? but how do you encode each field?

Thank you!

Yes, we don't have that derive macro yet. It's in the to do list.
