The documentation is not precise enough. It literally means "serialize as Array((K, V))", so you can use Vec<(String, String)> and so on here.

What's Map, serialize_map, and (most important!) Value in your example?

[loyd]

It's possible to support real maps (HashMap, BTreeMap, IndexMap etc) directly without using &[tuple], but it opens a large space for bugs because of #[serde(flatten)], serde_value::Value and other things which all should be handled correctly (or it ends with a lot of issues because of schema mismatch), that's not trivial.
