Struct webrender::print_tree::PrintTree

pub struct PrintTree<W>
where
    W: Write,
{
    level: u32,
    queued_item: Option<String>,
    line_buffer: String,
    sink: W,
}

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.
