Struct LeafTree

pub struct LeafTree<T>(/* private fields */);

Implementations

impl<T> LeafTree<T>

pub fn new() -> Self

pub fn add_folder( &mut self, path: &(impl AsRef<str> + ?Sized), ) -> Result<(), CosmicPathErr>

Adds a folder into the LeafTree. We removed the value argument in this wrapper, since all values for Folder data is ().

pub fn iter(&self) -> impl Iterator<Item = (String, UiTreeItemRef<'_, T, ()>)>

This is a wrapper around a standard iterator. Note that it skips the root value, which is always ().

pub fn files_paths(&self) -> impl Iterator<Item = (String, &T)>

This is a wrapper around a standard iterator. Note that it skips the root value, which is always ().

pub fn clear(&mut self)

Awaken afresh, as if it were all just a bad dream

Methods from Deref<Target = UiTree<T, ()>>

pub fn iter_paths( &self, ) -> impl Iterator<Item = (String, UiTreeItemRef<'_, T, F>)>

pub fn iter(&self) -> impl Iterator<Item = UiTreeItemRef<'_, T, F>>

Methods from Deref<Target = UiTreeFolder<T, F>>
