Struct jrsonnet_gcmodule::RawWeak

pub struct RawWeak<T: ?Sized, O: AbstractObjectSpace>(/* private fields */);

Low-level type for Weak<T>.

Implementations

impl<T: ?Sized, O: AbstractObjectSpace> RawWeak<T, O>

pub fn upgrade(&self) -> Option<RawCc<T, O>>

Attempts to obtain a “strong reference”.

Returns None if the value has already been dropped.

pub fn strong_count(&self) -> usize

Gets the reference count not considering weak references.

pub fn weak_count(&self) -> usize

Get the weak (non-owning) reference count.

pub fn ptr_eq(this: &Self, other: &Self) -> bool

Returns true if the two Weaks point to the same allocation

Trait Implementations

impl<T: ?Sized, O: AbstractObjectSpace> Clone for RawWeak<T, O>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized, O: AbstractObjectSpace> Drop for RawWeak<T, O>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: UnwindSafe + ?Sized, O: AbstractObjectSpace> UnwindSafe for RawWeak<T, O>
