Struct calloop::signals::Signals

pub struct Signals { /* private fields */ }

An event source for receiving Unix signals

Implementations

impl Signals

pub fn new(signals: &[Signal]) -> Result<Signals>

Create a new signal event source listening on the specified list of signals

pub fn add_signals(&mut self, signals: &[Signal]) -> Result<()>

Add a list of signals to the signals source

If this function returns an error, the signal mask of the thread may have still been changed.

pub fn remove_signals(&mut self, signals: &[Signal]) -> Result<()>

Remove a list of signals to the signals source

If this function returns an error, the signal mask of the thread may have still been changed.

pub fn set_signals(&mut self, signals: &[Signal]) -> Result<()>

Replace the list of signals of the source

If this function returns an error, the signal mask of the thread may have still been changed.

Trait Implementations

impl Drop for Signals

fn drop(&mut self)

Executes the destructor for this type.

impl EventSource for Signals

type Event = Event

The type of events generated by your sources

fn interest(&self) -> Ready

The interest value that will be given to mio when registering your source

fn pollopts(&self) -> PollOpt

The pollopt value that will be given to mio when registering your source

fn make_dispatcher<Data: 'static, F: FnMut(Event, &mut Data) + 'static>(
    &self,
    callback: F
) -> Rc<RefCell<dyn EventDispatcher<Data>>>

Wrap an user callback into a dispatcher, that will convert an mio readiness into an event

impl Evented for Signals

fn register(
    &self,
    poll: &Poll,
    token: Token,
    interest: Ready,
    opts: PollOpt
) -> Result<()>

Register self with the given Poll instance.

fn reregister(
    &self,
    poll: &Poll,
    token: Token,
    interest: Ready,
    opts: PollOpt
) -> Result<()>

Re-register self with the given Poll instance.

fn deregister(&self, poll: &Poll) -> Result<()>

Deregister self from the given Poll instance
