Struct StrongRc
pub struct StrongRc<T> { /* private fields */ }
Expand description
A strongly-held reference.
Similar to an alloc::sync::Arc
but holding a Strong
acts as a witness
to the live-ness of the underlying data. That is, holding a Strong
implies
that the underlying data has not yet been destroyed.
Note that Strong
’s implementation of Hash
and PartialEq
operate on
the pointer itself and not the underlying data.
Implementations§
§impl<T> Strong<T>
impl<T> Strong<T>
pub fn downgrade(_: &Strong<T>) -> Weak<T>
pub fn downgrade(_: &Strong<T>) -> Weak<T>
Returns a weak reference pointing to the same underlying data.
pub fn resource_token(&self) -> ResourceToken<'_>
pub fn resource_token(&self) -> ResourceToken<'_>
Returns a ResourceToken
that corresponds to this object.
pub fn marked_for_destruction(_: &Strong<T>) -> bool
pub fn marked_for_destruction(_: &Strong<T>) -> bool
Returns true if the inner value has since been marked for destruction.
pub fn weak_ptr_eq(_: &Strong<T>, _: &Weak<T>) -> bool
pub fn weak_ptr_eq(_: &Strong<T>, _: &Weak<T>) -> bool
Returns true if the two pointers point to the same allocation.
pub fn ptr_eq(_: &Strong<T>, _: &Strong<T>) -> bool
pub fn ptr_eq(_: &Strong<T>, _: &Strong<T>) -> bool
Returns true if the two pointers point to the same allocation.
pub fn debug_references(this: &Strong<T>) -> DebugReferences<T>
pub fn debug_references(this: &Strong<T>) -> DebugReferences<T>
Creates a DebugReferences
instance.
