Struct druid::Command

pub struct Command {
    pub selector: Selector,
    // some fields omitted
}

An arbitrary command.

A Command consists of a Selector, that indicates what the command is, and an optional argument, that can be used to pass arbitrary data.

Examples

use druid::{Command, Selector};

let selector = Selector::new("process_rows");
let rows = vec![1, 3, 10, 12];
let command = Command::new(selector, rows);

assert_eq!(command.get_object(), Some(&vec![1, 3, 10, 12]));

Fields
