Struct Message 

pub struct Message { /* private fields */ }

A sentence to show the user once, with an optional thing to do about it.

Message::new("Task deleted")
    .with_action("Undo", move |()| restore())
    .with_duration(MessageDuration::Long)
    .show();

Nothing here says where the message appears or what it looks like. Material calls it a snackbar, Apple a transient overlay, GNOME a toast: the design system decides, the same way it decides what a Dialog looks like.

Implementations

impl Message

pub fn new(text: impl Into<String>) -> Self

pub fn with_action( self, label: impl Into<String>, on_action: impl FnMut(()) + 'static, ) -> Self

Adds the one thing the user can do about the message, such as undoing it.

Call this from a component or an event handler: the callback is owned by the scope it is created in, which is what lets it touch that scope’s signals when it runs.

pub fn with_duration(self, duration: MessageDuration) -> Self

pub fn show(self)

Hands the message over. It goes out with the batch this call produces.
