Enum Subprotocol 

#[non_exhaustive]
pub enum Subprotocol {
    Spdy31Tunnel,
    LegacySpdy,
}

Protocol negotiated for a port-forward session.

Both variants speak the SPDY/3.1 frame format on the wire. They only differ in how frames reach the apiserver: tunnelled inside WebSocket binary messages, or sent straight over a raw HTTP/1.1 upgrade.

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.

Spdy31Tunnel

SPDY/3.1+portforward.k8s.io — SPDY frames tunnelled inside WebSocket binary messages. Negotiated via Sec-WebSocket-Protocol

LegacySpdy

Legacy SPDY/3.1 over a raw HTTP upgrade ( without WebSocket). Falls back here when the apiserver rejects the upgrade
