Trait Implementations

impl<T: ?Sized + ToOwned<Owned: Clone>> TempRepr for TempCow<T>

type Shared<'a> = Cow<'a, T> where Self: 'a

The type that Self is a temporary representation of. May contain shared references of lifetime 'a.

unsafe fn new_temp(obj: Self::Shared<'_>) -> Self

Converts the given object to its temporary representation.

fn get(&self) -> Self::Shared<'_>

Converts from a shared temporary reference back to the original type with a suitably-restricted lifetime.

impl<T: ?Sized + ToOwned<Owned: Clone>> TempReprMutChk for TempCow<T>

type SwapChkData = Option<NonNull<T>>

fn swap_chk_data(&self) -> Self::SwapChkData

Obtains an object (usually a copy of the internal state of self) that can be used to check whether self was swapped with another instance of Self in such a way that the safety rules of TempReprMutChk are violated.
