Struct FatalSignal 

pub struct FatalSignal { /* private fields */ }

One-per-node fail-fast signal. Any supervised transport-server task that exits unexpectedly trips it; the bin’s run loop selects on FatalSignal::tripped next to the OS shutdown signal and exits non-zero so an orchestrator restarts the node, instead of leaving a zombie whose peer/admin surface is dead while the consensus driver keeps running.

Implementations

impl FatalSignal

pub fn new() -> Self

A signal with no failure recorded.

pub fn trip(&self, component: &'static str)

Record that component’s server task died. The first trip wins — later trips keep the original component so the surfaced error names the root failure, not a teardown cascade.

pub fn check(&self) -> Option<&'static str>

The component whose server died, if any. Non-blocking.

pub async fn tripped(&self) -> &'static str

Resolve with the failed component once the signal trips. Pending forever while the node stays healthy.
