Expand description
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::channel::Sender;
use cursive::{Cursive, CursiveExt};
use cursive::views::TextView;
use cursive::utils::markup::StyledString;
use cursive_async_view::{AnimationProgressFrame, AsyncProgressView, AsyncProgressState};
fn my_progress_function(
_width: usize,
_height: usize,
progress: f32,
_pos: usize,
frame_idx: usize,
) -> AnimationProgressFrame {
AnimationProgressFrame {
content: StyledString::plain(format!("{:.0}%", progress * 100.0)),
pos: 0,
next_frame_idx: frame_idx,
}
}
let mut siv = Cursive::default();
let start = std::time::Instant::now();
let async_view = AsyncProgressView::new(&mut siv, move || {
if start.elapsed().as_secs() > 5 {
AsyncProgressState::Pending(start.elapsed().as_secs() as f32 /5f32)
} else {
AsyncProgressState::Available(TextView::new("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.
The pos
and frame_idx
parameter are always from the animation frame of the previous iteration.
