Required Methods

unsafe fn handle_closure( &self, signal: &ConnectDetails, callback: &Closure, ) -> Result<SignalHandlerId, BoolError>

fn remove_handle(&self, handle: SignalHandlerId)

fn handle<S, S_, C>(&self, signal: S_, callback: C) -> SignalHandlerId

where C: Fn(&Self, S::Arguments) -> <S::Return as ToValueOption>::Type, S: DetailedSignal, S_: Into<ConnectDetails<S>>, Self: Notifies<S::Signal>,

fn signal_stream<S, S_>(&self, signal: S_) -> SignalStream<Self, S::Arguments>

where S: DetailedSignal, S_: Into<ConnectDetails<S>>, Self: Notifies<S::Signal>, <S::Return as ToValueOption>::Type: Default,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
