Struct SignalState 

pub struct SignalState {
    pub handlers: BTreeMap<LinuxSignal, SignalAction>,
    pub blocked: SignalMask,
    pub pending: SignalMask,
}

Signal handler state for a task

Fields

handlers: BTreeMap<LinuxSignal, SignalAction>

Signal handlers (signal number -> handler action)

blocked: SignalMask

Blocked signals mask

pending: SignalMask

Pending signals that are blocked
