Macro println_tree 

macro_rules! println_tree {
    ($tree:expr $(,)?) => { ... };
    ($tree:expr, $style:expr $(,)?) => { ... };
}

Prints a type that implements DisplayTree to the standard output as a tree, with a newline.

A Style can be passed as the second argument to customize the way the tree is formatted.

Examples

use display_tree::println_tree;
println_tree!(tree)

Specifying a style:

use display_tree::{println_tree, Style, StyleBuilder};
println_tree!(tree, Style::default().indentation(1));
