sourcepub fn restart(&mut self)
pub fn restart(&mut self)
Restart the resource’s future.
Will not cancel the previous future, but will ignore any values that it generates.
sourcepub fn task(&self) -> Task
pub fn task(&self) -> Task
Get a handle to the inner task backing this resource Modify the task through this handle will cause inconsistent state
sourcepub fn finished(&self) -> bool
pub fn finished(&self) -> bool
Is the resource’s future currently finished running?
Reading this does not subscribe to the future’s state
sourcepub fn state(&self) -> ReadOnlySignal<UseResourceState>
pub fn state(&self) -> ReadOnlySignal<UseResourceState>
Get the current state of the resource’s future.
sourcepub fn value(&self) -> ReadOnlySignal<Option<T>>
pub fn value(&self) -> ReadOnlySignal<Option<T>>
Get the current value of the resource’s future.

§type Storage = UnsyncStorage

fn try_read_unchecked( &self ) -> Result<<<Resource<T> as Readable>::Storage as AnyStorage>::Ref<'static, <Resource<T> as Readable>::Target>, BorrowError>
Try to get a reference to the value without checking the lifetime. This will subscribe the current scope to the signal. Read more
source§fn peek_unchecked(
&self
) -> <<Resource<T> as Readable>::Storage as AnyStorage>::Ref<'static, <Resource<T> as Readable>::Target>
fn peek_unchecked( &self ) -> <<Resource<T> as Readable>::Storage as AnyStorage>::Ref<'static, <Resource<T> as Readable>::Target>
Get the current value of the signal without checking the lifetime. Unlike read, this will not subscribe the current scope to the signal which can cause parts of your UI to not update. Read more
source§fn map<O>(
self,
f: impl Fn(&Self::Target) -> &O + 'static
) -> MappedSignal<O, Self::Storage>
fn map<O>( self, f: impl Fn(&Self::Target) -> &O + 'static ) -> MappedSignal<O, Self::Storage>
Map the readable type to a new type.
source§fn read(&self) -> <Self::Storage as AnyStorage>::Ref<'_, Self::Target>
fn read(&self) -> <Self::Storage as AnyStorage>::Ref<'_, Self::Target>
Get the current value of the state. If this is a signal, this will subscribe the current scope to the signal.
If the value has been dropped, this will panic. Calling this on a Signal is the same as
using the signal() syntax to read and subscribe to its value
source§fn try_read(
&self
) -> Result<<Self::Storage as AnyStorage>::Ref<'_, Self::Target>, BorrowError>
fn try_read( &self ) -> Result<<Self::Storage as AnyStorage>::Ref<'_, Self::Target>, BorrowError>
Try to get the current value of the state. If this is a signal, this will subscribe the current scope to the signal.
source§fn read_unchecked(
&self
) -> <Self::Storage as AnyStorage>::Ref<'static, Self::Target>
fn read_unchecked( &self ) -> <Self::Storage as AnyStorage>::Ref<'static, Self::Target>
Get a reference to the value without checking the lifetime. This will subscribe the current scope to the signal. Read more
source§fn peek(&self) -> <Self::Storage as AnyStorage>::Ref<'_, Self::Target>
fn peek(&self) -> <Self::Storage as AnyStorage>::Ref<'_, Self::Target>
Get the current value of the state without subscribing to updates. If the value has been dropped, this will panic.
source§fn with<O>(&self, f: impl FnOnce(&Self::Target) -> O) -> O
fn with<O>(&self, f: impl FnOnce(&Self::Target) -> O) -> O
Run a function with a reference to the value. If the value has been dropped, this will panic.
