Struct GcPtr 

pub struct GcPtr<T> { /* private fields */ }

Implementations

impl<T> GcPtr<T>

pub unsafe fn from_raw(ptr: *const T) -> Self

Safety

• ptr must be non-null and correctly aligned for T.
• ptr must point to a valid instance of T allocated by RunMat’s GC and remain alive for the duration of all uses of the returned GcPtr.
• The caller is responsible for upholding aliasing and lifetime invariants when this pointer is dereferenced via Deref/DerefMut.

pub fn null() -> Self

pub fn is_null(&self) -> bool

pub unsafe fn as_raw(&self) -> *const T

Safety

The returned raw pointer may become invalid if the underlying object is collected by the GC. The caller must ensure the object is kept alive (e.g., via rooting) for any dereference, and must respect aliasing and lifetime rules when using the pointer.

pub unsafe fn as_raw_mut(&self) -> *mut T

Safety

Returns a mutable raw pointer to the underlying object. The caller must ensure exclusive access when mutating through this pointer, that the object outlives all uses, and that aliasing/lifetime invariants are respected. Mutating a collected or shared object is undefined behavior.

Trait Implementations

impl<T: Clone> Clone for GcPtr<T>

fn clone(&self) -> GcPtr<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for GcPtr<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Deref for GcPtr<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for GcPtr<T>
