Struct WeakElement 

pub struct WeakElement(/* private fields */);

Weak reference to an Element

(see the documentation of std::sync::Arc for an explanation of weak references)

This WeakElement can be held indefinitely without forcing the referenced data to remain valid. When access is needed, the method upgrade() will attempt to get a strong reference and return an Element

Implementations

impl WeakElement

pub fn upgrade(&self) -> Option<Element>

try to get a strong reference to the Element

Trait Implementations

impl Clone for WeakElement

fn clone(&self) -> WeakElement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WeakElement

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

Formats the value using the given formatter.

impl Hash for WeakElement

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 PartialEq for WeakElement

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

Tests for self and other values to be equal, and is used by ==.

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

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