Struct PointerState

Source

pub struct PointerState {
    pub pointer_buttons: HashMap<(PointerId, PointerButton), PointerButtonState>,
}

Expand description

State for all pointers.

Fields§

§pointer_buttons: HashMap<(PointerId, PointerButton), PointerButtonState>

Pressing and dragging state, organized by pointer and button.

Implementations§

Source §

impl PointerState

Source

pub fn get( &self, pointer_id: PointerId, button: PointerButton, ) -> Option<&PointerButtonState>

Retrieves the current state for a specific pointer and button, if it has been created.

Source

pub fn get_mut( &mut self, pointer_id: PointerId, button: PointerButton, ) -> &mut PointerButtonState

Provides write access to the state of a pointer and button, creating it if it does not yet exist.

Source

pub fn clear(&mut self, pointer_id: PointerId)

Clears all the data assoceated with all of the buttons on a pointer. Does not free the underlying memory.

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
