Struct GcHeap 

pub struct GcHeap { /* private fields */ }

Backward-compatible GC heap interface backed by ObjectSlab.

All mark-sweep semantics have been removed. Objects are reference-counted and freed deterministically when no references remain.

Implementations

impl GcHeap

pub fn new(_collection_threshold: usize) -> Self

Create a new heap. The _collection_threshold parameter is accepted for API compatibility but ignored (no automatic collection in RC mode).

pub fn alloc<T: Any + 'static>(&mut self, value: T) -> GcRef

Allocate a value on the heap, returning a handle.

pub fn alloc_auto<T: Any + 'static>( &mut self, value: T, _roots: &[GcRef], ) -> GcRef

Allocate with “auto-collection” — for API compat. The _roots parameter is ignored (no GC to trigger).

pub fn get<T: Any + 'static>(&self, gc_ref: GcRef) -> Option<&T>

Read a reference to the value behind gc_ref, downcasting to T.

pub fn collect(&mut self, _roots: &[GcRef])

No-op: mark-sweep has been removed. Objects are reference-counted.

pub fn live_count(&self) -> usize

Number of live objects on the heap.

pub fn capacity(&self) -> usize

Total capacity (number of slots, including freed ones).

pub fn free_list(&self) -> &[usize]

Access the free list (for backward compat with tests).

pub fn free(&mut self, gc_ref: GcRef)

Explicitly free a slot.

Trait Implementations

impl Debug for GcHeap

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

Formats the value using the given formatter.

impl Default for GcHeap

fn default() -> Self

Returns the “default value” for a type.
