fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Borrow<T> for DoesNotHaveToBeUsed<T>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T: Clone> Clone for DoesNotHaveToBeUsed<T>

fn clone(&self) -> DoesNotHaveToBeUsed<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for DoesNotHaveToBeUsed<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for DoesNotHaveToBeUsed<T>

fn default() -> DoesNotHaveToBeUsed<T>

Returns the “default value” for a type.

impl<T> Deref for DoesNotHaveToBeUsed<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T> DerefMut for DoesNotHaveToBeUsed<T>

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

Mutably dereferences the value.

impl<T> From<T> for DoesNotHaveToBeUsed<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for DoesNotHaveToBeUsed<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> PartialEq for DoesNotHaveToBeUsed<T>

fn eq(&self, other: &DoesNotHaveToBeUsed<T>) -> 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.
