Struct TreeFormatting

pub struct TreeFormatting {
    pub prefix_str: Option<String>,
    pub orientation: TreeOrientation,
    pub anchor: AnchorPosition,
    pub chars: FormatCharacters,
}

This structure collects together all the formatting options that control how the tree is output.

Fields

prefix_str: Option<String>

A prefix string written before every line. While no validation is performed on this value, if newline (or other formatting) characters are included the tree is likely to appear disjointed.

orientation: TreeOrientation

The orientation to write the tree.

anchor: AnchorPosition

The line anchor position.

chars: FormatCharacters

The set of characters to use when line formatting.
