Enum freya::prelude::TreeItem

pub enum TreeItem<I, V> {
    Expandable {
        id: I,
        value: V,
        state: ExpandableItemState<I, V>,
    },
    Standalone {
        id: I,
        value: V,
    },
}

Item part of a larget Tree.

Expandable can be expanded/open, e.g folders Standalone cannot be expanded/opened, e.g files

Variants

Expandable

Fields

id: I

Implementations

impl<I, V> TreeItem<I, V>

where I: ItemPath + Clone, V: Clone + PartialEq,

pub fn id(&self) -> &I

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

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.

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.

Trait Implementations

impl<I, V> Clone for TreeItem<I, V>

where I: Clone, V: Clone,

fn clone(&self) -> TreeItem<I, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I, V> Debug for TreeItem<I, V>

where I: Debug, V: Debug,

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

Formats the value using the given formatter.

impl<I, V> PartialEq for TreeItem<I, V>

where I: PartialEq, V: PartialEq,

fn eq(&self, other: &TreeItem<I, V>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
