Struct HitTargetSpec 

pub struct HitTargetSpec<'a, I> {
    pub shape: Option<RoundedCornerShape>,
    pub click_actions: I,
    pub pointer_inputs: &'a [Rc<dyn Fn(PointerEvent)>],
    pub pointer_icon: Option<&'a PointerIcon>,
}

What a hit target answers with: the shape that narrows its bounds, the handlers it dispatches to, and the pointer icon it asks for while hovered.

Fields

shape: Option<RoundedCornerShape>

Narrows the target’s rectangle to a rounded shape, so a point in a corner cutout misses it.

click_actions: I

Click handlers, invoked on an unconsumed press inside the target.

pointer_inputs: &'a [Rc<dyn Fn(PointerEvent)>]

Raw pointer handlers, invoked for every event the target receives.

pointer_icon: Option<&'a PointerIcon>

The pointer’s appearance while it hovers this target.
