Struct ConnectHandle 

pub struct ConnectHandle { /* private fields */ }

Handle representing a typed signal connection to a receiver.

Returned by connections made by the connect_* methods of TypedSignal and ConnectBuilder.

Connections managed by a handle can be disconnected using disconnect().

Implementations

impl ConnectHandle

pub fn disconnect(self)

Disconnects the signal from the connected callable.

Panics (safeguards-balanced)

If the connection does not exist. Use is_connected() to make sure the connection exists.

pub fn is_connected(&self) -> bool

Whether the handle represents a valid connection.

Returns false if:

• … the signals and callables managed by this handle have been disconnected in any other way than by using disconnect() – e.g. through Signal::disconnect() or Object::disconnect().
• … the broadcasting object managed by this handle is not valid – e.g. if the object has been freed.
