Struct cxx::UniquePtr [−][src]
#[repr(C)]pub struct UniquePtr<T> where
T: UniquePtrTarget, { /* fields omitted */ }
Expand description
Binding to C++ std::unique_ptr<T, std::default_delete<T>>
.
Implementations
Makes a new UniquePtr wrapping a null pointer.
Matches the behavior of default-constructing a std::unique_ptr.
Allocates memory on the heap and makes a UniquePtr pointing to it.
Checks whether the UniquePtr does not own an object.
This is the opposite of std::unique_ptr<T>::operator bool.
Returns a reference to the object owned by this UniquePtr if any, otherwise None.
Returns a mutable pinned reference to the object owned by this UniquePtr if any, otherwise None.
Returns a mutable pinned reference to the object owned by this UniquePtr.
Panics
Panics if the UniquePtr holds a null pointer.
Consumes the UniquePtr, releasing its ownership of the heap-allocated T.
Matches the behavior of std::unique_ptr<T>::release.
Constructs a UniquePtr retaking ownership of a pointer previously
obtained from into_raw
.
Safety
This function is unsafe because improper use may lead to memory problems. For example a double-free may occur if the function is called twice on the same raw pointer.
