Enum AnySession 

#[non_exhaustive]
pub enum AnySession<P: Protocol> {
    Configured(Session<P, Configured>),
    Authenticated(Session<DPlus, Authenticated>),
    Connecting(Session<P, Connecting>),
    Connected(Session<P, Connected>),
    Disconnecting(Session<P, Disconnecting>),
    Closed(Session<P, Closed>),
}

Storage-friendly enum wrapping a Session<P, S> in any state.

Use this when you need to keep a session in a struct field that might be in any state (e.g., a long-lived REPL state). For individual transitions, use the typed Session<P, S> directly.

Note: AnySession<P> is generic over the protocol. The Self::Authenticated variant is hard-coded to DPlus because the typestate guarantees only DPlus reaches that state. This is a known wart of full typestate that we accept.

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.

Configured(Session<P, Configured>)

Configured state — session built but no I/O has happened.

Authenticated(Session<DPlus, Authenticated>)

Authenticated state — DPlus only, TCP auth completed.

Connecting(Session<P, Connecting>)

Connecting state — LINK packet sent, waiting for ACK.

Connected(Session<P, Connected>)

Connected state — operational.

Disconnecting(Session<P, Disconnecting>)

Disconnecting state — UNLINK sent, waiting for ACK.

Closed(Session<P, Closed>)

Closed state — terminal.
