Struct cxx::WeakPtr[−][src]

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

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

[src]

impl<T> WeakPtr<T> where
T: WeakPtrTarget,

[src]

pub fn null() -> Self

Makes a new WeakPtr wrapping a null pointer.

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

[src]

pub fn upgrade(&self) -> SharedPtr<T> where
T: SharedPtrTarget,

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.
