pub struct PrintTree<W>where
    W: Write,{

    queued_item: Option<String>,
    line_buffer: String,
    sink: W,
}
Expand description

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.

§line_buffer: String§sink: W

The sink to print to.
