Struct Delegate 

pub struct Delegate<T> { /* private fields */ }

A multicast delegate: the handlers of an event in the order they were added. Public for the connections that are implemented outside this library (the ones of the designer support), which keep their handlers in one as the connections here do.

Implementations

impl<T> Delegate<T>

pub fn new() -> Delegate<T>

pub fn is_null(&self) -> bool

_delegate == null.

pub fn add(&mut self, handler: Handler<T>) -> HandlerToken

_delegate += handler.

pub fn remove(&mut self, token: HandlerToken)

_delegate -= handler.

pub fn snapshot(&self) -> Vec<Handler<T>>

The handlers as they are now, to invoke them outside a lock.

Trait Implementations

impl<T> Default for Delegate<T>

fn default() -> Self

Returns the “default value” for a type.
