Struct calloop::generic::Generic

pub struct Generic<E: Evented + 'static> { /* fields omitted */ }

A generic event source wrapping an Evented type

It will simply forward the readiness and an acces to the wrapped Evented type to the suer callback. See the Event type in this module.

Methods

impl<E: Evented + 'static> Generic<E>

pub fn new(source: E) -> Generic<E>

Wrap a Evented type into a Generic event source

It is initialized with no interest nor poll options, as such you should set them using the set_interest and set_pollopts methods before inserting it in the event loop.

pub fn set_interest(&mut self, interest: Ready)

Change the interest for this evented source

If the source was already inserted in an event loop, it needs to be re-registered for the change to take effect.

pub fn set_pollopts(&mut self, pollopts: PollOpt)

Change the poll options for this evented source

If the source was already inserted in an event loop, it needs to be re-registered for the change to take effect.

pub fn unwrap(self) -> Rc<RefCell<E>>

Unwrap the Generic source to retrieve the underlying Evented.

If you didn't clone the Rc<RefCell<E>> from the Event<E> you received, the returned Rc should be unique.

impl<Fd: AsRawFd> Generic<EventedFd<Fd>>

pub fn from_fd_source(source: Fd) -> Generic<EventedFd<Fd>>

Wrap a file descriptor based source into a Generic event source.

This will only work with poll-compatible file descriptors, which typically not include basic files.

Trait Implementations

impl<E: Evented + 'static> Evented for Generic<E>

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

impl<E: Evented + 'static> EventSource for Generic<E>

type Event = Event<E>

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<E>, &mut Data) + 'static>(     &self,     callback: F ) -> Rc<RefCell<EventDispatcher<Data>>>

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