Struct PollingSignals

pub struct PollingSignals { /* private fields */ }

A filesystem path based way to poll for ‘signals’. Cloning makes another receiver that checks independently from the original (but both receive the same ‘signals’).

Implementations

impl PollingSignals

pub fn open(path: &Path, initial_value: u64) -> Result<Self, IPCAtomicError>

pub fn get_number_of_signals(&mut self) -> u64

Check how many signals were received since the last check.

pub fn got_signals(&mut self) -> bool

Check whether there were any signals (just get_number_of_signals() > 0)

pub fn send_signal(&mut self) -> u64

Send one signal. This is excluded from this PollingSignals instance, i.e. get_number_of_signals() will not report it. Returns the previous value.

pub fn sender(&self) -> PollingSignalsSender
