Required Methods

fn is_moved(&self) -> bool

Check if this event means that the pointer device as moved while hovering a node.

fn is_enter(&self) -> bool

Check if this event means that the pointer device started hovering a node.

fn is_pressed(&self) -> bool

Check if this event means that the pointer device was pressed while hovering a node.

fn is_released(&self) -> bool

Check if this event means that the pointer device was released while hovering and hovering a node.

fn is_global(&self) -> bool

Check if this event is global, where global means that an event will be emitted to every node independently of where they are or how they are.

fn does_bubble(&self) -> bool

Check if this event bubbles, where bubbling means that an ancestor of the event node will be called with the same event unless the event node stops the bubbling.

fn does_go_through_solid(&self) -> bool

Check if this event can go through solid surfaces, e.g keyboard events.

fn new_leave() -> Self

Create a new event that means the pointer device left a hovering node.

fn new_exclusive_leave() -> Self

Create a new exclusive leave event for when the deepest (entered) node changes without the node necessarily leaving the cursor area entirely.

fn new_exclusive_enter() -> Self

Create a new exclusive leave event for when the deepest (entered) node changes without the node necessarily leaving the cursor area entirely.

fn get_derived_events(&self) -> HashSet<Self>

Get a set of events derived from this event. For example, mouse movement derives into mouse movement + mouse enter.

Provided Methods

fn is_exclusive_enter(&self) -> bool

Check if this enter event should only fire on the deepest (most specific) node, not on all nodes under the cursor simultaneously.

fn is_exclusive_leave(&self) -> bool

Check if this leave event corresponds to an exclusive enter

fn get_global_events(&self) -> HashSet<Self>

Get a set of global events derived from this event.

fn get_cancellable_events(&self) -> HashSet<Self>

Get a set of events that will be discarded once this event is cancelled.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
