Struct StoreObserver

pub struct StoreObserver { /* private fields */ }

Use ditto.store().register_observer(...) to create an observer with a callback.

Implementations

impl StoreObserver

pub fn query_string(&self) -> String

Return the query string used to create this StoreObserver.

pub fn query_arguments(&self) -> Option<Value>

Return the query arguments used to create this StoreObserver, if any.

pub fn cancel(&self)

Cancels this StoreObserver and its callback.

The callback registered with this StoreObserver will no longer be called after calling .cancel().

This call is a no-op if this StoreObserver has already been cancelled or if the owning Ditto object has gone out of scope.

pub fn is_cancelled(&self) -> bool

Returns true if this StoreObserver has been cancelled.

Trait Implementations

impl Hash for StoreObserver

fn hash<H: Hasher>(&self, h: &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 StoreObserver

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.
