Enum BackendConnectionRoute 

pub enum BackendConnectionRoute {
    HelloSkip,
    BrokerNegotiated,
    HandlePassed,
}

How connect_to_backend reached the returned backend endpoint.

Variants

HelloSkip

Connected directly to a known backend endpoint, skipping Hello.

Used for the cached-endpoint fast path and, deliberately reused to avoid a new enum variant (a semver hazard for exhaustive matches), for the RUNNING_PROCESS_FAKE_BACKEND_ENV test seam. A fake-backend connection is distinguishable because the caller set the env var and BackendConnection::endpoint equals its value.

BrokerNegotiated

Asked the broker via Hello, then connected to the negotiated endpoint.

HandlePassed

Adopted the existing broker connection after a confirmed handoff.

The broker handed the client’s connection to the backend (DuplicateHandle/SCM_RIGHTS) and relayed the backend’s accepted HandoffAck back to the client, so the socket that carried Hello is now served by the backend. No connection to backend_pipe was opened; BackendConnection::endpoint still reports the negotiated backend_pipe so callers can cache it for future Hello-skip.

Trait Implementations

impl Clone for BackendConnectionRoute

fn clone(&self) -> BackendConnectionRoute

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for BackendConnectionRoute

impl Debug for BackendConnectionRoute

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Eq for BackendConnectionRoute

impl PartialEq for BackendConnectionRoute

fn eq(&self, other: &BackendConnectionRoute) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
