Implementations§

source§

impl<I, V> TreeItem<I, V>
where I: ItemPath + Clone, V: Clone + PartialEq,

source

pub fn id(&self) -> &I

Get the ID of the item, e.g its path.

source

pub fn set_state(&mut self, item_id: &I, item_state: &ExpandableItemState<I, V>)

Update the state of the given Expandable Item, e.g to open with more items or to simply close.

source

pub fn flat(&self, depth: usize, root_id: &I) -> Vec<FlatItem<I>>

Turn all the inner items and this item itself into a flat list. This can be useful for virtualization.
