Struct Gc 

pub struct Gc<T: ?Sized> { /* private fields */ }

A GC-managed pointer. Copy + Clone (one-machine-word). Replaces GcRef<T>.

Implementations

impl<T: Trace + 'static> Gc<T>

pub fn new_uncollected(value: T) -> Self

Allocate a GcBox<T> outside any heap registry. Used by legacy GcRef::new call sites until Phase D-1b migrates them. The returned Gc<T> is reachable only through the caller’s own retention path; without joining a heap’s allgc chain, it will never be swept (so effectively leaks until process exit — same as Rc behavior).

impl<T: ?Sized> Gc<T>

pub fn ptr_eq(a: Self, b: Self) -> bool

Two Gc<T>s are identity-equal iff they point at the same box.

pub fn identity(self) -> usize

Identity as a usize — usable as a hash table key for “is the same object” lookups.

Trait Implementations

impl<T: ?Sized> AsRef<T> for Gc<T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: ?Sized> Clone for Gc<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized> Debug for Gc<T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Deref for Gc<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: ?Sized> Hash for Gc<T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: ?Sized> PartialEq for Gc<T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: Trace + 'static> Trace for Gc<T>

Gc<T> is itself traceable: marking it forwards to the contained T.

fn trace(&self, m: &mut Marker)

impl<T: ?Sized> Copy for Gc<T>

impl<T: ?Sized> Eq for Gc<T>
