#[repr(C)]
pub struct WeakPtr<T> where
    T: WeakPtrTarget
{ /* private fields */ }
Expand description

Binding to C++ std::weak_ptr<T>.

The typical way to construct a WeakPtr from Rust is by downgrading from a SharedPtr.

Implementations

Makes a new WeakPtr wrapping a null pointer.

Matches the behavior of default-constructing a std::weak_ptr.

Upgrades a non-owning reference into an owning reference if possible, otherwise to a null reference.

Matches the behavior of std::weak_ptr<T>::lock.
