`AutocompleteState`

查看源码

pub fn new(items: impl IntoIterator<Item = PickerItem<T>>) -> Result<Self, PickerError>

with_layoutpub fn with_layout(mut self, layout: AutocompletePopoverLayout) -> Self—

Configures with layout for this part.

pub fn with_layout(mut self, layout: AutocompletePopoverLayout) -> Self

查看源码

with_filter_modepub fn with_filter_mode(mut self, filter_mode: PickerFilterMode) -> Self—

Configures with filter mode for this part.

pub fn with_filter_mode(mut self, filter_mode: PickerFilterMode) -> Self

查看源码

with_filterpub fn with_filter(mut self, filter: PickerFilter) -> Self—

Install an application-supplied filter predicate before a runtime context exists. This is Base UI's `filter` prop. The predicate replaces [`Self::filter_mode`] entirely; [`Self::set_filter`] passing `None` restores it.

pub fn with_filter(mut self, filter: PickerFilter) -> Self

查看源码

with_valuepub fn with_value(mut self, value: impl Into<Arc<str>>) -> Self—

Set the initial free-form value before a runtime context exists. This is the constructor-time equivalent of [`Self::set_value`]: a state that has never been mounted owns no popover to synchronize, so no [`EventContext`] is needed. The value is bounded by [`MAX_AUTOCOMPLETE_VALUE_BYTES`] exactly as it is at runtime.

pub fn with_value(mut self, value: impl Into<Arc<str>>) -> Self

查看源码

layoutpub const fn layout(&self) -> AutocompletePopoverLayout—

Configures layout for this part.

pub const fn layout(&self) -> AutocompletePopoverLayout

查看源码

set_layoutpub fn set_layout(&mut self, layout: AutocompletePopoverLayout, cx: &mut EventContext) -> bool—

Replace native popover geometry, closing an open fixed-size child first.

pub fn set_layout(&mut self, layout: AutocompletePopoverLayout, cx: &mut EventContext) -> bool

查看源码

selection_behaviorpub const fn selection_behavior(&self) -> AutocompleteSelectionBehavior—

Configures selection behavior for this part.

set_valuepub fn set_value(&mut self, value: impl Into<Arc<str>>, cx: &mut EventContext) -> bool—

Replace the free-form value and recompute or forward the bounded suggestion query.

查看源码

set_items

pub fn set_items( &mut self, items: impl IntoIterator<Item = PickerItem<T>>, cx: &mut EventContext, ) -> Result<(), PickerError>

—

Atomically replace suggestions and update an open child without reopening its surface.

查看源码

filterpub fn filter(&self) -> Option<&PickerFilter>—

The application-supplied filter predicate, when one is installed.

pub fn filter(&self) -> Option<&PickerFilter>

查看源码

set_filterpub fn set_filter(&mut self, filter: Option<PickerFilter>, cx: &mut EventContext) -> bool—

Replace the built-in filter policy with an application-supplied predicate. Passing `None` restores [`Self::filter_mode`]. The open suggestion surface, if any, is resynchronized exactly once.

pub fn set_filter(&mut self, filter: Option<PickerFilter>, cx: &mut EventContext) -> bool

Build the autocomplete against a per-instance retained-state accessor. A host that renders many declared autocompletes through one view passes an accessor that captures which [`AutocompleteState`] each registered listener resolves.
