Struct LineNumbers 

pub struct LineNumbers {
    pub relative: bool,
    pub align: Alignment,
    pub main_align: Alignment,
    pub show_wraps: bool,
    /* private fields */
}

Shows a column of line numbers beside the Buffer

There are various fields that you can use to configure how the LineNumbers will be displayed. They control things like the line numbers and the relativeness of the number displayed.

This is a default struct of Duat, that is, it is automatically placed around every Buffer, but you can disable that behavior by removing the "BufferWidgets" hook.
