Enum EventHandler 

pub enum EventHandler {
    NoArgs(Rc<RefCell<dyn FnMut()>>),
    MouseEvent(Rc<RefCell<dyn FnMut(MouseEvent)>>),
    UnsupportedSignature(EventAttribFn),
}

Event handlers such as the closure in onclick = |event| {}.

Cloning

Can be cheaply cloned since since inner types are reference counted.

Variants

NoArgs(Rc<RefCell<dyn FnMut()>>)

A callback that does not contain any arguments.

MouseEvent(Rc<RefCell<dyn FnMut(MouseEvent)>>)

Handle mouse events such as onclick and oninput

UnsupportedSignature(EventAttribFn)

EventHandler’s that we do not have a dedicated type for. This is useful for custom events.

Trait Implementations

impl Clone for EventHandler

fn clone(&self) -> EventHandler

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EventHandler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EventHandler

fn eq(&self, _other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
