Struct relm4::abstractions::Toaster

pub struct Toaster { /* private fields */ }

Available on crate feature libadwaita only.

An abstraction over adw::ToastOverlay that makes it easy to store it in the model of components.

The only allowed action is to add toasts, effectively keeping the separation between UI and application state.
