Crate bin_tree

Building a binary tree from an iterator.

Examples

use bin_tree::{IteratorEx, Node};

#[derive(Clone, Default, PartialEq, Eq, Debug)]
struct NodeStr(String);

impl Node for NodeStr {
    fn new_parent(self, right: Self) -> Self {
        Self("[".to_owned() + &self.0 + ", " + &right.0 + "]")
    }
    fn new_parent_from_single(self) -> Self {
        self
    }
}

let x = (0..10).map(|v| NodeStr(v.to_string())).build_tree();
assert_eq!(x, Some(NodeStr("[[[[0, 1], [2, 3]], [[4, 5], [6, 7]]], [8, 9]]".to_string())));

Traits

• IteratorEx
  The trait extends the functionality of the standard Iterator trait by adding the build_tree method.
