Struct base::print_tree::PrintTree

pub struct PrintTree {
    level: u32,
    queued_item: Option<String>,
}

A struct that makes it easier to print out a pretty tree of data, which can be visually scanned more easily.

Fields

level: u32

The current level of recursion.

queued_item: Option<String>

An item which is queued up, so that we can determine if we need a mid-tree prefix or a branch ending prefix.
