Struct SelectionValue 

#[non_exhaustive]
pub struct SelectionValue<'a> {
    pub selected_items: &'a [SharedString],
    pub selected_indices: &'a [usize],
    pub selected_keys: Option<&'a [SharedString]>,
    pub selected_text: &'a str,
    pub is_placeholder: bool,
    pub default_children: AnyElement,
}

v3’s value render props, as one value.

Select.Value, Autocomplete.Value and ComboBox.Value all hand their children a function and pass in {defaultChildren, isPlaceholder, selectedItems, selectedText}. defaultChildren is what the slot would have drawn, so a caller can wrap it instead of rebuilding it – which is what v3’s own examples do (if (isPlaceholder) return defaultChildren).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

selected_items: &'a [SharedString]

selectedItems — the chosen items’ text. The order is the component’s selection order: Select walks the collection, while ComboBox and Autocomplete follow their selection set’s insertion order, the way pinned react-stately 3.49.0’s Set iterates.

selected_indices: &'a [usize]

Where those items sit in the collection, for a caller keyed by index, in the same order as selected_items.

selected_keys: Option<&'a [SharedString]>

The chosen items’ keys, in selection insertion order, when the component’s collection is keyed and those keys are distinct from the labels (Autocomplete, ComboBox). Select is index-keyed and carries no distinct key here. selected_items and selected_indices only contain entries for keys that currently resolve to collection items, so async-loaded or missing keys can make their lengths differ from selected_keys.

selected_text: &'a str

selectedText — the same items joined. Select approximates v3’s en-US list formatter; the other two use plain comma-space in this port.

is_placeholder: bool

isPlaceholder — nothing is chosen, so the placeholder shows.

default_children: AnyElement

defaultChildren — the element this slot would have drawn.
