[][src]Struct event_manager::EventManager

pub struct EventManager<T> { /* fields omitted */ }

Allows event subscribers to be registered, connected to the event loop, and later removed.

Implementations

impl<S: MutEventSubscriber> EventManager<S>[src]

pub fn new() -> Result<Self>[src]

Create a new EventManger object.

pub fn new_with_capacity(ready_events_capacity: usize) -> Result<Self>[src]

Creates a new EventManger object with specified event capacity.

Arguments

  • ready_events_capacity : maximum number of ready events to be process in a single poll

pub fn run(&mut self) -> Result<usize>[src]

Run the event loop blocking until events are triggered or an error is returned. Calls subscriber.process() for each event.

On success, it returns number of dispatched events or 0 when interrupted by a signal.

pub fn run_with_timeout(&mut self, milliseconds: i32) -> Result<usize>[src]

Wait for events for a maximum timeout of miliseconds or until an error is returned. Calls subscriber.process() for each event.

On success, it returns number of dispatched events or 0 when interrupted by a signal.

Trait Implementations

impl<T: MutEventSubscriber> SubscriberOps for EventManager<T>[src]

type Subscriber = T

Subscriber type for which the operations apply.

fn add_subscriber(&mut self, subscriber: T) -> SubscriberId[src]

Register a subscriber with the event event_manager and returns the associated ID.

fn remove_subscriber(&mut self, subscriber_id: SubscriberId) -> Result<T>[src]

Unregisters and returns the subscriber associated with the provided ID.

fn subscriber_mut(&mut self, subscriber_id: SubscriberId) -> Result<&mut T>[src]

Return a mutable reference to the subscriber associated with the provided id.

fn event_ops(&mut self, subscriber_id: SubscriberId) -> Result<EventOps<'_>>[src]

Returns a EventOps object for the subscriber associated with the provided ID.
