Struct SearchableVec 

pub struct SearchableVec<T> { /* private fields */ }

A vector of items that supports incremental filtering.

On each perform_search call the matched_items view is rebuilt by filtering the full items list. Use this as a delegate when all data is already in memory.

Implementations

impl<T: Clone> SearchableVec<T>

pub fn new(items: impl Into<Vec<T>>) -> Self

Create a new SearchableVec from an initial list of items.

pub fn push(&mut self, item: T)

Append an item to both the master list and the current filtered view.

Trait Implementations

impl<T: Clone> Clone for SearchableVec<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for SearchableVec<T>

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

impl<T: SearchableListItem> From<Vec<T>> for SearchableVec<T>

fn from(items: Vec<T>) -> Self

Converts to this type from the input type.

impl<I: SearchableListItem + 'static> SearchableListDelegate for SearchableVec<I>

type Item = I

fn items_count(&self, _: usize) -> usize

Number of items in the given section.

fn item(&self, ix: IndexPath) -> Option<&Self::Item>

Return a reference to the item at the given index path.

fn position<V>(&self, value: &V) -> Option<IndexPath>

where Self::Item: SearchableListItem<Value = V>, V: PartialEq,

Find the index path of the item whose value equals value.

fn perform_search( &mut self, query: &str, _: &mut Window, _: &mut App, ) -> Task<()>

Called when the search query changes.

fn sections_count(&self, _: &App) -> usize

Number of sections (groups) in the list. Defaults to 1.

fn section(&self, _section: usize) -> Option<AnyElement>

👎Deprecated

Optional header element for the given section index.

fn render_item( &self, _ix: IndexPath, _item: &Self::Item, _checked: bool, _window: &mut Window, _cx: &mut App, ) -> Option<AnyElement>

Override the row content for the item at ix.

fn render_section_header( &self, _section: usize, _window: &mut Window, _cx: &mut App, ) -> Option<AnyElement>

Render the header element for the given section (full render access).

fn is_item_enabled(&self, _ix: IndexPath, item: &Self::Item, _cx: &App) -> bool

Whether the item at ix should be rendered as interactive.

fn is_item_checked( &self, _ix: IndexPath, item: &Self::Item, current_selection: &[(IndexPath, Self::Item)], _cx: &App, ) -> bool

Whether the item at ix should show a checkmark.

fn on_will_change( &mut self, selection: &mut Vec<(IndexPath, Self::Item)>, changes: &[SearchableListChange], )

Called before a user-triggered selection change is committed.

fn on_confirm(&mut self, _final_selection: &[(IndexPath, Self::Item)])

Called when the dropdown/popover is committed (Escape, close_on_select, or explicit confirm). final_selection is the selection after the last committed change.
