Struct BoxElement 

pub struct BoxElement<'s> { /* private fields */ }

An element with its type erased.

This type can be used to return multiple kinds of elements from a function.

Example

use line_ui::element::{BoxElement, IntoElement};
use line_ui::{Color, Style};

fn foo(value: bool) -> BoxElement<'static> {
    if value {
        "some fancy text"
            .fixed_width(20)
            .styled(Style::fg(Color::RED) + Style::INVERT)
            .boxed()
    } else {
        "just some text".boxed()
    }
}
