Crate ego_tree

Vec-backed ID-tree.

Behavior

• Trees have at least a root node;
• Nodes have zero or more ordered children;
• Nodes have at most one parent;
• Nodes can be detached (orphaned) but not removed;
• Node parent, next sibling, previous sibling, first child and last child can be accessed in constant time;
• All methods perform in constant time;
• All iterators perform in linear time.

Examples

let mut tree = ego_tree::Tree::new('a');
let mut root = tree.root_mut();
root.append('b');
let mut c = root.append('c');
c.append('d');
c.append('e');

#[macro_use] extern crate ego_tree;
let tree = tree!('a' => { 'b', 'c' => { 'd', 'e' } });
