Struct ArcLocalSignal 

pub struct ArcLocalSignal<T: 'static>(/* private fields */);

A local variant of an ArcSignal, that will panic if accessed from a different thread.

Used for the [QueryClient::subscribe_value_arc_local] return type.

Implementations

impl<T> ArcLocalSignal<T>

pub fn derive_local(derive_fn: impl Fn() -> T + 'static) -> Self

Like ArcSignal::derive, but the value is not threadsafe and will panic if accessed from a different thread.

Trait Implementations

impl<T> Clone for ArcLocalSignal<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ArcLocalSignal<T>

where T: Debug + 'static,

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

Formats the value using the given formatter.

impl<T> DefinedAt for ArcLocalSignal<T>

fn defined_at(&self) -> Option<&'static Location<'static>>

Returns the location at which the signal was defined. This is usually simply None in release mode.

impl<T: Clone> From<ArcLocalSignal<T>> for Signal<T, LocalStorage>

fn from(value: ArcLocalSignal<T>) -> Self

Converts to this type from the input type.

impl<T> ReadUntracked for ArcLocalSignal<T>

type Value = ReadGuard<T, Mapped<<ArcSignal<SendWrapper<T>> as ReadUntracked>::Value, T>>

The guard type that will be returned, which can be dereferenced to the value.

fn try_read_untracked(&self) -> Option<Self::Value>

Returns the guard, or None if the signal has already been disposed.

fn read_untracked(&self) -> Self::Value

Returns the guard.

fn custom_try_read(&self) -> Option<Option<Self::Value>>

This is a backdoor to allow overriding the Read::try_read implementation despite it being auto implemented.

impl<T> Track for ArcLocalSignal<T>

fn track(&self)

Subscribes to this signal in the current reactive scope without doing anything with its value.
