Trait WidgetExt 

pub trait WidgetExt:
    Widget
    + Sized
    + 'static {
    // Provided method
    fn tooltip(self, label: impl Into<String>) -> Tooltip { ... }
}

Ergonomic extension available on EVERY widget (D115/Phase 32): attach a tooltip as a PROPERTY instead of wrapping — Button::new("Save") .tooltip("Saves changes"). Desktop shows it on hover; mobile has no hover, so it’s naturally inert there (a long-press variant can hook the same path later). Styling comes from the theme’s TooltipStyle.

Provided Methods

fn tooltip(self, label: impl Into<String>) -> Tooltip

Show label while the pointer hovers this widget.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
