Struct Loader 

pub struct Loader<T>
where
    T: 'static,
{ /* private fields */ }

A Loader is a signal that represents a value that is loaded asynchronously.

Once a Loader<T> has been successfully created from use_loader, it can be use like a normal signal of type T.

When the loader is re-reloading its values, it will no longer suspend its component, making it very useful for server-side-rendering.

Implementations

impl<T> Loader<T>

where T: 'static,

pub fn error(&self) -> Option<CapturedError>

Get the error that occurred during loading, if any.

After initial load, this will return None until the next reload fails.

pub fn restart(&mut self)

Restart the loading task.

After initial load, this won’t suspend the component, but will reload in the background.

pub fn is_error(&self) -> bool

Check if the loader has failed.

pub fn cancel(&mut self)

Cancel the current loading task.

pub fn loading(&self) -> bool

Trait Implementations

impl<T> Clone for Loader<T>

fn clone(&self) -> Loader<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Loader<T>

where T: Debug + 'static + PartialEq,

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

Formats the value using the given formatter.

impl<T> Deref for Loader<T>

where T: Clone + PartialEq + 'static,

type Target = dyn Fn() -> T

The resulting type after dereferencing.

fn deref(&self) -> &<Loader<T> as Deref>::Target

Dereferences the value.

impl<T> Display for Loader<T>

where T: Display + 'static + PartialEq,

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

Formats the value using the given formatter.

impl<T> IntoAttributeValue for Loader<T>

where T: Clone + IntoAttributeValue + PartialEq + 'static,

fn into_value(self) -> AttributeValue

Convert into an attribute value

impl<T> IntoDynNode for Loader<T>

where T: Clone + IntoDynNode + PartialEq + 'static,

fn into_dyn_node(self) -> DynamicNode

Consume this item and produce a DynamicNode

impl<T> PartialEq<T> for Loader<T>

where T: PartialEq + 'static,

fn eq(&self, other: &T) -> 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<T> PartialEq for Loader<T>

where T: 'static,

fn eq(&self, other: &Loader<T>) -> 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<T> Readable for Loader<T>

fn try_peek_unchecked( &self, ) -> Result<<<Loader<T> as Readable>::Storage as AnyStorage>::Ref<'static, <Loader<T> as Readable>::Target>, BorrowError>

where T: 'static,

Get the current value of the signal. Unlike read, this will not subscribe the current scope to the signal which can cause parts of your UI to not update.

If the signal has been dropped, this will panic.

type Target = T

The target type of the reference.

type Storage = UnsyncStorage

The type of the storage this readable uses.

fn try_read_unchecked( &self, ) -> Result<<<Loader<T> as Readable>::Storage as AnyStorage>::Ref<'static, <Loader<T> as Readable>::Target>, BorrowError>

where T: 'static,

Try to get a reference to the value without checking the lifetime. This will subscribe the current scope to the signal.

fn subscribers(&self) -> Subscribers

where T: 'static,

Get the underlying subscriber list for this readable. This is used to track when the value changes and notify subscribers.

impl<T> Writable for Loader<T>

where T: 'static,

type WriteMetadata = <Signal<Option<T>> as Writable>::WriteMetadata

Additional data associated with the write reference.

fn try_write_unchecked( &self, ) -> Result<WriteLock<'static, <Loader<T> as Readable>::Target, <Loader<T> as Readable>::Storage, <Loader<T> as Writable>::WriteMetadata>, BorrowMutError>

where <Loader<T> as Readable>::Target: 'static,

Try to get a mutable reference to the value without checking the lifetime. This will update any subscribers.

impl<T> Copy for Loader<T>
