Struct runa_orbiter::utils::WeakPtr

pub struct WeakPtr<T>(_);

A wrapper of Weak that implements Hash and Eq by comparing raw pointer addresses.

Implementations

impl<T> WeakPtr<T>

pub fn from_rc(t: &Rc<T>) -> Self

Create a WeakPtr by downgrading a Rc.

pub fn new() -> Self

Create an empty WeakPtr.

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

Attempt to upgrade the WeakPtr to an Rc.

pub fn into_inner(self) -> Weak<T>

Return the inner Weak.

pub const fn as_weak(&self) -> &Weak<T>

Get a reference to the inner Weak.

Trait Implementations

impl<T> Clone for WeakPtr<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for WeakPtr<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> From<Weak<T>> for WeakPtr<T>

fn from(value: Weak<T>) -> Self

Converts to this type from the input type.

impl<T> Hash for WeakPtr<T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq<WeakPtr<T>> for WeakPtr<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
