Trait which provides methods for querying the tree.

Required Methods

fn parent(&self, tree: &Tree<I>) -> Option<I>

fn first_child(&self, tree: &Tree<I>) -> Option<I>

fn is_sibling(&self, tree: &Tree<I>, entity: I) -> bool

fn is_child_of(&self, tree: &Tree<I>, entity: I) -> bool

fn is_descendant_of(&self, tree: &Tree<I>, entity: I) -> bool

fn parent_iter<'a>(&self, tree: &'a Tree<I>) -> LayoutParentIterator<'a, I>

fn child_iter<'a>(&self, tree: &'a Tree<I>) -> LayoutChildIterator<'a, I>

fn tree_iter<'a>(&self, tree: &'a Tree<I>) -> TreeIterator<'a, I>

fn branch_iter<'a>(&self, tree: &'a Tree<I>) -> TreeIterator<'a, I>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
