Struct cell_gc::ptr::UntypedPointer

pub struct UntypedPointer(_);

Similar to Pointer<T> but provides no guarantees other than that it points to some allocation inside the GC heap, and has the minimal GC-required alignment.

Safety

See Pointer<T>.

Methods

impl UntypedPointer

unsafe fn as_typed_ptr<T>(&self) -> Pointer<T>

Convert this UntypedPointer into a Pointer<T>.

Safety

You had better be damn sure that this pointer points at a T instance. See also the Pointer<T> safety rules and its new method's safety rules.

fn is_null(&self) -> bool

Is this pointer null?

fn as_void(&self) -> *const ()

Get the underlying raw pointer.

fn as_usize(&self) -> usize

Get the underlying raw pointer as a usize.
