Struct PresenceObserver

pub struct PresenceObserver { /* private fields */ }

Use ditto.presence().register_observer(...) to create a new PresenceObserver.

Example

use dittolive_ditto::Ditto;

// To register a new presence observer
let observer = ditto.presence().register_observer(|graph| {
    println!("Graph updated: {:?}", graph);
})?;

// Later, to cancel the observer
observer.cancel();

Implementations

impl PresenceObserver

pub fn cancel(&self)

Cancels this PresenceObserver. The registered callback will no longer be called.

pub fn is_cancelled(&self) -> bool

Returns whether this PresenceObserver has been cancelled.

Trait Implementations

impl Hash for PresenceObserver

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PresenceObserver

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
