Function for_each_output

pub fn for_each_output(for_each: impl FnMut(&OutputHandle) + Send + 'static)

Runs a closure on all current and future outputs.

When called, this will do two things:

1. Immediately run for_each with all currently connected outputs.
2. Call for_each with any newly connected outputs.

Note that for_each will not run with outputs that have been unplugged and replugged. This is to prevent duplicate setup. Instead, the compositor keeps track of any tags and state the output had when unplugged and restores them on replug. This may change in the future.

Examples

// Add tags 1-3 to all outputs and set tag "1" to active
output::for_each_output(|op| {
    let mut tags = tag::add(op, ["1", "2", "3"]);
    tags.next().unwrap().set_active(true);
});
