Struct Timeline 

pub struct Timeline { /* private fields */ }

Things along time, on named tracks, under a ruler with markers and a playhead.

It holds nothing: the app gives it what is there and where the playhead is, and gets back what people do. Blocks are buttons, so they work with the keyboard. Dragging the ruler moves the playhead, dragging a movable block moves it, and the ends of a trimmable one change its length.

use ravenrs_widgets::{Timeline, TimelineItem, TimelineTrack, Tone};

let timeline = Timeline::new(vec![
    TimelineTrack::new("Notes", 34.0, vec![TimelineItem::new(1, 2_000, 3_000, "Callout").movable()]),
    TimelineTrack::new("Film", 56.0, vec![TimelineItem::new(2, 0, 10_000, "Take 1").tone(Tone::Accent)]),
])
.position_ms(4_000)
.on_seek(|ms| println!("{ms}"));

Implementations
