Function encode_position_event 

pub fn encode_position_event(
    event: &PositionEvent,
) -> Result<EncodedPayload, EncodeError>

Encodes a [PositionEvent] envelope by dispatching on the variant.

publish_position_event hands the bus tap a [PositionEvent] wrapper, so the tap dispatches by the wrapper’s std::any::TypeId and the inner variants never reach their bare-type encoders. The dispatcher unwraps each variant, encodes the inner struct, and stamps the inner-variant tag so forensics scans see entries identical to the bare-type capture path.

Errors

Returns the inner encoder’s EncodeError when MessagePack rejects the inner payload.
