Enum ListenerMode 

pub enum ListenerMode {
    Connection,
    Session,
}

How a [serve.listeners.<name>] drives each accepted connection (cap-req 08). See ListenerConfig::mode.

Variants

Connection

Long-lived tcp-connection-handler — one wasm instance pinned per connection for its whole life (the original inbound-TCP model). The default.

Session

Re-entrant session-handler — the host owns the socket and drives it through the session model, holding NO instance between inbound batches (idle ⇒ socket + checkpoint only). A quiet, PARKED connection (blocked on the socket read between batches) is NOT evicted for inactivity — only the absolute max_conn_duration_ms cap and dead-peer detection (EOF) end it, so a protocol-idle but alive peer (IMAP IDLE) survives. In this mode idle_timeout_ms is reinterpreted as the per-re-entry processing deadline — the max wall-clock ONE re-entry may spend (instantiate + handle + write its response) — bounding a guest stalled on a slow/zero-window peer so it cannot pin a session-pool slot + instance; a re-entry that exceeds it is cancelled and the connection closed. Re-entries run on a DEDICATED concurrency pool, never the shared async lane.
