Function sequence 

pub fn sequence(cmds: Vec<Option<Cmd>>) -> Option<Cmd>

Sequence commands to run one at a time, in order.

Unlike batch, sequenced commands run one after another. Use this when the order of execution matters.

Example

use bubbletea::{Cmd, Message, sequence};

let cmd = sequence(vec![
    Some(Cmd::new(|| Message::new("first"))),
    Some(Cmd::new(|| Message::new("second"))),
]);
