Struct Announcer 

pub struct Announcer { /* private fields */ }

Where an application says what changed. A handle: clones say it in the same place.

use ravenrs_app_a11y::{Announcer, Urgency};
use ravenrs_core::Role;
use ravenrs_widgets::Ui;

let announcer = Announcer::new();
let mut ui = Ui::new(announcer.region(), ravenrs_style::Theme::raven_dark());
announcer.polite("Salvo: Conta corrente");
ui.update();
assert!(ui.access_tree().find(Role::Status, "Salvo: Conta corrente").is_some());
announcer.assertive("Não foi salvo");
ui.update();
assert!(ui.access_tree().find(Role::Alert, "Não foi salvo").is_some());
assert_eq!(announcer.latest().map(|a| a.urgency), Some(Urgency::Assertive));
