Struct PrintLine 

pub struct PrintLine<'a> { /* private fields */ }

A Line, drawn on the first row of the area it’s rendered into and clipped to area.width() columns. Only the first row is used.

align defaults to Align::Left (drawn at the left edge); set it with PrintLine::align to right-align or center the whole line’s spans as a unit within area.width() columns.

Examples

use retroglyph_core::backend::Headless;
use retroglyph_core::text::Line;
use retroglyph_core::{Rect, Terminal};
use retroglyph_widgets::{PrintLine, Widget};

let mut term = Terminal::new(Headless::new(20, 1));
let line = Line::raw("hello");
term.draw(|surface| {
    PrintLine::new(&line).render(Rect::new(0, 0, 20, 1), surface);
})
.unwrap();
