Function every 

pub fn every<F>(duration: Duration, f: F) -> Cmd
where
    F: FnOnce(Instant) -> Message + Send + 'static,

Command that ticks in sync with the system clock.

Unlike tick, this aligns with the system clock. For example, if you tick every second and the clock is at 12:34:20.5, the next tick will happen at 12:34:21.0 (in 0.5 seconds).

Example

use bubbletea::{Cmd, every, Message};
use std::time::{Duration, Instant};

struct TickMsg(Instant);

fn tick_every_second() -> Cmd {
    every(Duration::from_secs(1), |t| Message::new(TickMsg(t)))
}
