Struct ebri::ref_counted::RefCounted

pub struct RefCounted<T> { /* private fields */ }

RefCounted stores an instance of type T, and a union of a link to the next Collectible or the reference counter.

Implementations

impl<T> RefCounted<T>

pub fn try_add_ref(&self, order: Ordering) -> bool

Tries to add a strong reference to the underlying instance.

order must be as strong as Acquire for the caller to correctly validate the newest state of the pointer.

pub fn get_mut_shared(&mut self) -> Option<&mut T>

Returns a mutable reference to the instance if the number of owners is 1.

pub fn get_mut_unique(&mut self) -> &mut T

Returns a mutable reference to the instance if it is uniquely owned.

pub fn add_ref(&self)

Adds a strong reference to the underlying instance.

pub fn drop_ref(&self) -> bool

Drops a strong reference to the underlying instance.

Returns true if it the last reference was dropped.

pub fn ref_cnt(&self) -> &AtomicUsize

Returns a reference to its reference count.

pub fn as_collectible(&self) -> &dyn Collectible

Returns a dyn Collectible reference to self.

fn drop_and_dealloc(&mut self)

Drops itself and frees the memory.

impl<T> Deref for RefCounted<T>

type Target = T
