Enum TransportPreference 

#[non_exhaustive]
pub enum TransportPreference {
    WsFirst,
    SseFirst,
    WsOnly,
    SseOnly,
}

Transport preference for the client connection.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WsFirst

Try WebSocket first, fall back to SSE if unavailable.

SseFirst

Try SSE first, fall back to WebSocket if unavailable.

WsOnly

WebSocket only — fail if upgrade is rejected.

SseOnly

SSE only — client→server via POST /ack endpoint.
