}

The unified content union, discriminated by the type tag.

This is the Rust equivalent of the Python Contents union.

The Content::Unknown variant makes deserialization forward-compatible: a content item whose type tag is not one of the known variants deserializes to Unknown rather than failing the whole message. This mirrors Python’s parse-and-skip behavior for unknown content (_types.py:2205-2210), except the item is retained as an inert placeholder instead of being dropped. Unknown carries no data, so it re-serializes as {"type":"unknown"} (the original tag/fields are not preserved) and is treated as inert everywhere: it yields no text, no function call, and is ignored by aggregation/coalescing.
