Struct glib::object::SendWeakRef

source · [−]

pub struct SendWeakRef<T: ObjectType>(_, _);

Expand description

A weak reference to the object it was created for that can be sent to different threads even for object types that don’t implement Send.

Trying to upgrade the weak reference from another thread than the one where it was created on will panic but dropping or cloning can be done safely from any thread.

Implementations

source

impl<T: ObjectType> SendWeakRef<T>

source

pub fn new() -> SendWeakRef<T>

source

pub fn into_weak_ref(self) -> WeakRef<T>

Methods from Deref<Target = WeakRef<T>>

source

pub fn set(&self, obj: Option<&T>)

Set this weak reference to the given object.

source

pub fn upgrade(&self) -> Option<T>

Try to upgrade this weak reference to a strong reference.

If the stored object was already destroyed or no object was set in this weak reference then None is returned.
