Trait Element 

pub trait Element<'s> {
    // Required methods
    fn width(&self) -> usize;
    fn render(&self) -> impl DoubleEndedIterator<Item = RenderChunk<'s>>;
}

A particular widget that can be rendered to the TUI.

Lifetime parameter

The 's lifetime parameter indicates the lifetime of any values (e.g., strings) borrowed by the Element. For example:

use line_ui::element::Text;

let my_string = String::from("hello");
let my_element = Text::new(&my_string);

Here, my_element implements Element<'s>, where 's is the lifetime of my_string.

Required Methods

fn width(&self) -> usize

The width of the element, in columns.

fn render(&self) -> impl DoubleEndedIterator<Item = RenderChunk<'s>>

Renders the element into a sequence of chunks.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
