Struct SigWrapper 

pub struct SigWrapper(pub i32);

A signal the scheduler can name, INCLUDING the realtime signals nix cannot.

⚠️ WHY THIS IS A RAW i32 AND NOT A nix::Signal. It used to be SigWrapper(pub Signal), and nix’s Signal models only 1..=31. Every cross-task notification path gated on Signal::try_from(raw), so a tgkill/tkill/rt_tgsigqueueinfo/rt_sigqueueinfo carrying SIGRTMIN..SIGRTMAX delivered the signal to the target and then SILENTLY skipped NotifySignalPending. Measured in-tree: the gate admitted exactly 1..=31 and ZERO of the 31 realtime signals. A thread parked on ResourceID::WaitChild was therefore never woken and the wait hung — permanently, until the child exited or the thread was killed.

The two rt_*sigqueueinfo sites are the sharp end: they are reached from sigqueue()/pthread_sigqueue(), which are used with realtime signals in essentially all real code, so those notification call sites were wired up and inert for their only normal use.

⚠️ THE SERIALIZED FORM IS DELIBERATELY UNCHANGED FOR EVERY SIGNAL THAT COULD ALREADY BE REPRESENTED. 1..=31 still render as the nix name ("SIGUSR1"), byte-for-byte as before, so existing schedule files and DETLOG output do not move. Only the previously-impossible values gain a spelling, "SIG<n>", and the deserializer accepts both. This is what keeps a model-type widening from becoming a schedule-compatibility break.

Implementations

impl SigWrapper

pub fn raw(&self) -> i32

The raw signal number, always available.

pub fn signal(&self) -> Option<Signal>

The nix signal, when one exists. None for realtime signals: they are real, deliverable, and simply unnamed by nix.

pub fn as_string(&self) -> String

How this signal is spelled in schedule files and DETLOG.
