A point-in-time view of this tunnel and its process-shared relay budget. Non-exhaustive: fields are added as the SDK observes more.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

relay_transport: RelayTransport

The carrier this tunnel reaches the relay over, fixed when it started.

direct: Option<PathDiagnostics>

port_mapping: Option<PortMappingDiagnostics>

Present when the tunnel maps its direct endpoint’s port: asked for, with direct allowed.

sdk_version: &'static str

last_attempt_phase: RecoveryPhase

Most recent worker phase; use tunnel status for aggregate readiness.

attempts: u64

consecutive_failures: u64

last_failure: Option<RecoveryFailure>

last_success_age_ms: Option<u64>

Time since the last authenticated relay reply, even a negative reply.

last_setup_latency_ms: Option<u64>

Last answered setup latency, excluding admission queue time.

next_retry_in_ms: Option<u64>

dns_age_ms: Option<u64>

network_generation: u64

active_control_setups: usize

Shared across this process for the same configured relay address.

active_data_setups: usize

events: Vec<TunnelEvent>

The latest outcomes, oldest first; at most 16 entries. Steps along the way are only in TunnelEvents; see TunnelEventKind.
