    T: GcTrace + ?Sized + 'static,
{ /* private fields */ }

Implementations

impl<T> GcWeak<T>

where T: GcTrace + ?Sized,

pub fn is_valid(&self) -> bool

pub fn try_deref(&self) -> Option<&T>

pub fn mark_trace(&self)

pub fn ptr_eq<U>(self_weak: &GcWeak<T>, other_weak: &GcWeak<U>) -> bool

where U: GcTrace + ?Sized,

pub fn as_id(self_weak: &GcWeak<T>) -> usize

This is intended for identifying the GcWeak, and should not be cast back to a pointer.
