Struct Selection 

pub struct Selection<'a, T: Send + Sync + 'static> { /* private fields */ }

The selected items when the picker quits.

This is the return type of the various pick_multi* methods of a Picker. Iterate over the picked items with iter. If no items were selected, ththe struct will be empty. Also see the docs on multiple selections

The lifetime of this struct is bound to the lifetime of the picker from which it originated.

Implementations

impl<'a, T: Send + Sync + 'static> Selection<'a, T>

pub fn iter(&self) -> impl ExactSizeIterator<Item = &'a T> + DoubleEndedIterator

Returns an iterator over the other selected items.

The iterator contains each selected item exactly once, sorted by index based on the order in which the picker received the items. Note that items are deduplicated based on the selection index instead of using any properties of the type T itself.

The iterator will be empty if the picker quit without selecting any items.

pub fn is_empty(&self) -> bool

Returns if there were no selected items.

pub fn len(&self) -> usize

Returns the number of selected items.
