Struct relm4::factory::AsyncFactoryVecDeque

pub struct AsyncFactoryVecDeque<C: AsyncFactoryComponent>where
    <C::ParentWidget as FactoryView>::ReturnedWidget: Clone,{ /* private fields */ }

A container similar to VecDeque that can be used to store data associated with components that implement AsyncFactoryComponent.

To access mutable methods of the factory, create a guard using Self::guard.

Implementations

impl<C: AsyncFactoryComponent> AsyncFactoryVecDeque<C>where
    <C::ParentWidget as FactoryView>::ReturnedWidget: Clone,

pub fn new(
    widget: C::ParentWidget,
    parent_sender: &Sender<C::ParentInput>
) -> Self

Creates a new AsyncFactoryVecDeque.

pub fn guard(&mut self) -> AsyncFactoryVecDequeGuard<'_, C>

Provides a AsyncFactoryVecDequeGuard that can be used to edit the factory.

The changes will be rendered on the widgets after the guard goes out of scope.

pub fn len(&self) -> usize

Returns the number of elements in the AsyncFactoryVecDeque.

pub fn is_empty(&self) -> bool

Returns true if the AsyncFactoryVecDeque is empty.

pub fn send(&self, index: usize, msg: C::Input)

Send a message to one of the elements.

pub fn broadcast(&self, msg: C::Input)where
    C::Input: Clone,

Send clone of a message to all of the elements.

pub fn get(&self, index: usize) -> Option<&C>

Tries to get an immutable reference to the model of one element.

Returns None if index is invalid or the async init_model() method hasn’t returned yet.

pub fn back(&self) -> Option<&C>

Provides a reference to the model of the back element.

Returns None if index is invalid or the async init_model() method of the last element hasn’t returned yet.

pub fn front(&self) -> Option<&C>

Provides a reference to the model of the front element.

Returns None if index is invalid or the async init_model() method of the first element hasn’t returned yet.

pub const fn widget(&self) -> &C::ParentWidget

Returns the widget all components are attached to.

pub fn iter(
    &self
) -> impl Iterator<Item = Option<&C>> + DoubleEndedIterator + ExactSizeIterator + FusedIterator

Returns an iterator over the components.

Each item will be Some if the async init_model() method of the item returned and otherwise None.

impl<C: Debug + AsyncFactoryComponent> Debug for AsyncFactoryVecDeque<C>where
    <C::ParentWidget as FactoryView>::ReturnedWidget: Clone,
    C::ParentWidget: Debug,
    C::ParentInput: Debug,

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

Formats the value using the given formatter.

impl<C: AsyncFactoryComponent> Drop for AsyncFactoryVecDeque<C>where
    <C::ParentWidget as FactoryView>::ReturnedWidget: Clone,

fn drop(&mut self)

Executes the destructor for this type.
