Struct ori_core::CallbackEmitter
source · pub struct CallbackEmitter<T = ()> { /* private fields */ }
Expand description
A Callback
emitter.
This is used to store a list of callbacks and call them all. All the callbacks are weak, so they must be kept alive by the user.
Implementations§
source§impl<T> CallbackEmitter<T>
impl<T> CallbackEmitter<T>
sourcepub fn downgrade(&self) -> WeakCallbackEmitter<T>
pub fn downgrade(&self) -> WeakCallbackEmitter<T>
Downgrades the callback emitter to a WeakCallbackEmitter
.
sourcepub fn subscribe(&self, callback: &Callback<'_, T>)
pub fn subscribe(&self, callback: &Callback<'_, T>)
Subscribes a callback to the emitter.
The reference to the callback is weak, and will therefore not keep the callback alive. If the callback is dropped, it will be removed from the emitter.
sourcepub fn subscribe_weak(&self, callback: WeakCallback<T>)
pub fn subscribe_weak(&self, callback: WeakCallback<T>)
Subscribes a weak callback to the emitter.
