Struct leak_playground_std::marker::Unforget

#[repr(transparent)]
pub struct Unforget<'a, T: ?Sized> {
    _unforget: PhantomStaticUnforget,
    _anchor: PhantomData<fn(_: &'a ())>,
    inner: T,
}

A transparent wrapper to make your types !Forget

Fields

_unforget: PhantomStaticUnforget

_anchor: PhantomData<fn(_: &'a ())>

Inner value must be able to outlive this lifetime to be able to be forgotten. Of course it is contravariant, since expanding it may only disable the Forget implementation.

inner: T

Implementations

impl<T> Unforget<'static, T>

pub const fn new(inner: T) -> Self

impl<'a, T> Unforget<'a, T>

pub fn with_lifetime(inner: T) -> Self

pub fn into_inner(slot: Self) -> T

Get inner value.

Trait Implementations

impl<'a, T: Clone + ?Sized> Clone for Unforget<'a, T>

fn clone(&self) -> Unforget<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized + Debug> Debug for Unforget<'_, T>

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

Formats the value using the given formatter.

impl<'a, T: Default + ?Sized> Default for Unforget<'a, T>

fn default() -> Unforget<'a, T>

Returns the “default value” for a type.

impl<T: ?Sized> Deref for Unforget<'_, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: ?Sized> DerefMut for Unforget<'_, T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> Future for Unforget<'_, T>

where T: Future + ?Sized,

type Output = <T as Future>::Output

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl<'a, T: Hash + ?Sized> Hash for Unforget<'a, T>

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

Feeds this value into the given Hasher.

impl<'a, T: Ord + ?Sized> Ord for Unforget<'a, T>

fn cmp(&self, other: &Unforget<'a, T>) -> Ordering

This method returns an Ordering between self and other.

impl<'a, T: PartialEq + ?Sized> PartialEq for Unforget<'a, T>

fn eq(&self, other: &Unforget<'a, T>) -> 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.

impl<'a, T: PartialOrd + ?Sized> PartialOrd for Unforget<'a, T>

fn partial_cmp(&self, other: &Unforget<'a, T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
