Trait Implementations

impl Clone for AnySubscriber

fn clone(&self) -> AnySubscriber

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AnySubscriber

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for AnySubscriber

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 AnySubscriber

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.

impl ReactiveNode for AnySubscriber

fn mark_dirty(&self)

Notifies the source’s dependencies that it has changed.

fn mark_subscribers_check(&self)

Marks that all subscribers need to be checked.

fn update_if_necessary(&self) -> bool

Regenerates the value for this node, if needed, and returns whether it has actually changed or not.

fn mark_check(&self)

Notifies the source’s dependencies that it may have changed.

impl Subscriber for AnySubscriber

fn add_source(&self, source: AnySource)

Adds a subscriber to this subscriber’s list of dependencies.

fn clear_sources(&self, subscriber: &AnySubscriber)

Clears the set of sources for this subscriber.

impl ToAnySubscriber for AnySubscriber

fn to_any_subscriber(&self) -> AnySubscriber

Converts this type to its type-erased equivalent.

impl WithObserver for AnySubscriber

fn with_observer<T>(&self, fun: impl FnOnce() -> T) -> T

Runs the given function with this subscriber as the thread-local Observer.

fn with_observer_untracked<T>(&self, fun: impl FnOnce() -> T) -> T

Runs the given function with this subscriber as the thread-local Observer, but without tracking dependencies.
