Struct Weak 

pub struct Weak<T: ?Sized = Erased> {
    pub type_name: &'static str,
    /* private fields */
}

Weak reference. Doesn’t affect reference counting.

Fields

Trait Implementations

impl<T: ?Sized> Clone for Weak<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized + Debug> Debug for Weak<T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Default for Weak<T>

default fn default() -> Self

Returns the “default value” for a type.

impl<T> Default for Weak<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: ?Sized> Deref for Weak<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: ?Sized> DerefMut for Weak<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T: Managed> ExistsManaged for Weak<T>

fn exists_managed(&self) -> bool

impl<T> Hash for Weak<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 for Weak<T>

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.

impl<T, U> CoerceUnsized<Weak<U>> for Weak<T>

where T: Unsize<U> + ?Sized, U: ?Sized,

impl<T: ?Sized> Copy for Weak<T>

impl<T> Eq for Weak<T>
