Struct Gc

pub struct Gc<T>
where
    T: GcTrace + ?Sized + 'static,
{ /* private fields */ }

! Smart pointer to GCed data. See the module-level documentation for more details.

Implementations

impl<T: GcTrace> Gc<T>

pub fn new(data: T) -> Self

impl<T> Gc<T>

where T: GcTrace + ?Sized + Pointee, T::Metadata: Into<PtrMetadata>, GcBox<T>: Pointee<Metadata = T::Metadata>,

pub fn from_box(data: Box<T>) -> Self

impl<T> Gc<T>

where T: GcTrace + ?Sized,

pub fn ptr_eq<U>(self_gc: &Gc<T>, other_gc: &Gc<U>) -> bool

where U: GcTrace + ?Sized,

pub fn as_id(self_gc: &Gc<T>) -> usize

Casts the inner pointer to a usize. This is intended for identifying the Gc, and should not be cast back to a pointer.

impl<T> Gc<T>

where T: GcTrace + ?Sized, PtrMetadata: TryInto<<GcBox<T> as Pointee>::Metadata>,

pub fn weakref(&self) -> GcWeak<T>

Create a weak reference from this GC handle
