Struct RatatuiLogo

Source 
pub struct RatatuiLogo { /* private fields */ }
Expand description

A widget that renders the Ratatui logo

The Ratatui logo takes up two lines of text and comes in two sizes: Tiny and Small. This may be used in an application’s help or about screen to show that it is powered by Ratatui.

§Examples

The Ratatui-logo example demonstrates how to use the RatatuiLogo widget. This can be run by cloning the Ratatui repository and then running the following command with an optional size argument:

cargo run --example ratatui-logo [size]

§Tiny (default, 2x15 characters)

use ratatui::widgets::RatatuiLogo;

frame.render_widget(RatatuiLogo::tiny(), frame.area());

Renders:

▛▚▗▀▖▜▘▞▚▝▛▐ ▌▌
▛▚▐▀▌▐ ▛▜ ▌▝▄▘▌

§Small (2x27 characters)

use ratatui::widgets::RatatuiLogo;

frame.render_widget(RatatuiLogo::small(), frame.area());

Renders:

█▀▀▄ ▄▀▀▄▝▜▛▘▄▀▀▄▝▜▛▘█  █ █
█▀▀▄ █▀▀█ ▐▌ █▀▀█ ▐▌ ▀▄▄▀ █
