UnsafePtr

v8::cppgc

Struct UnsafePtr 

Source 
pub struct UnsafePtr<T: GarbageCollected> { /* private fields */ }
Expand description

UnsafePtr is used to refer to an on-heap object from the stack.

Implementations§

Source§

impl<T: GarbageCollected> UnsafePtr<T>

Source

pub unsafe fn new(value: &impl GetRustObj<T>) -> Option<UnsafePtr<T>>

Create a new UnsafePtr.

§Safety

The caller must ensure that the returned pointer is always stored on the stack, or is safely moved into one of the other cppgc pointer types.

Source

pub unsafe fn as_ref(&self) -> &T
