Function cursive_async_view::default_progress

pub fn default_progress(
    width: usize, 
    _height: usize, 
    progress: f32
) -> StyledString

The default progress animation for a AsyncProgressView.

Creating your own progress function

As an example a very basic progress function would look like this:

use crossbeam::Sender;
use cursive::Cursive;
use cursive::views::TextView;
use cursive::utils::markup::StyledString;
use cursive_async_view::AsyncProgressView;

fn my_progress_function(
    _width: usize,
    _height: usize,
    progress: f32,
) -> StyledString {
    StyledString::plain(format!("{:.0}%", progress * 100.0))
}

let mut siv = Cursive::default();
let async_view = AsyncProgressView::new(&siv, |s: Sender<f32>| {
    std::thread::sleep(std::time::Duration::from_secs(1));
    s.send(0.2).unwrap();
    std::thread::sleep(std::time::Duration::from_secs(1));
    s.send(0.4).unwrap();
    std::thread::sleep(std::time::Duration::from_secs(1));
    s.send(0.6).unwrap();
    std::thread::sleep(std::time::Duration::from_secs(1));
    s.send(0.8).unwrap();
    std::thread::sleep(std::time::Duration::from_secs(1));
    s.send(1.0).unwrap();
    TextView::new("Yay, the content has loaded!")
})
.with_progress_fn(my_progress_function);

The progress function will display the progress in percent as a simple string.

The width and height parameters contain the maximum size the content may have (in characters). The progress parameter is guaranteed to be a f32 between 0 and 1.
