pub struct StoreObserver { /* private fields */ }

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

Implementations

impl StoreObserver

pub fn cancel(&self)

Cancels the observation. The handler that was passed in when registering this store observer will no longer be called. No-op if this store observer is already cancelled or the owning Ditto object goes out of scope. 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.

impl Drop for StoreObserver

fn drop(&mut self)

Executes the destructor for this type.

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

This method tests for self and other values to be equal, and is used by ==.

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

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