Struct WeakRef

pub struct WeakRef<T: GcCell> { /* private fields */ }

Weak reference wrapper.

Implementations

impl<T: GcCell> WeakRef<T>

pub fn upgrade(&self) -> Option<GcPointer<T>>

Trait Implementations

impl<T: GcCell> Clone for WeakRef<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: GcCell> GcCell for WeakRef<T>

fn compute_size(&self) -> usize

Used when object has dynamic size i.e arrays

fn type_name(&self) -> &'static str

impl<T: GcCell> TraceTrait for WeakRef<T>

fn trace(&self, vis: &mut Visitor)

Function invoking the tracing for an object of type T.

extern "C" fn trace_(vis: *mut Visitor, this: *const u8)

trace_ method is used for C FFI safety.

fn get_trace_descriptor(this: *const u8) -> TraceDescriptor

Returns trace descriptor for type that implements this trait. Not recommended to override it.
