Required Methods§

fn to_signal(&self) -> Value<'_, Self>

This is the opposite of Signal::to_signal_hook.

In contrast to Hook::use_hook, this method just require a &Self instead of Pin<&mut Self>. In implementations, Hook::use_hook might mark the SignalHook’s updated value as already read but this method should not.
