Trait Implementations

impl<'b, B: ?Sized> AsRef<B> for Borrowed<'b, B>

fn as_ref(&self) -> &B

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

impl<'b, B: ?Sized> Borrow<B> for Borrowed<'b, B>

fn borrow(&self) -> &B

Immutably borrows from an owned value.

impl<'b, B: Debug + ?Sized> Debug for Borrowed<'b, B>

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

Formats the value using the given formatter.

impl<'b, B: ?Sized> Deref for Borrowed<'b, B>

type Target = B

The resulting type after dereferencing.

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

Dereferences the value.

impl<'b, B: Hash + ?Sized> Hash for Borrowed<'b, B>

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<'b, B> IntoOwning for Borrowed<'b, B>

where B: ToOwning + ?Sized,

fn into_owning(self) -> Self::Owning

Converts an object which owns its contents into one which borrows them.

impl<'b, B: Ord + ?Sized> Ord for Borrowed<'b, B>

fn cmp(&self, other: &Borrowed<'b, B>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'b, B: PartialEq + ?Sized> PartialEq for Borrowed<'b, B>

fn eq(&self, other: &Borrowed<'b, B>) -> 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<'b, B: PartialOrd + ?Sized> PartialOrd for Borrowed<'b, B>

fn partial_cmp(&self, other: &Borrowed<'b, B>) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl<'b, B> StaticCow<B> for Borrowed<'b, B>

where B: ToOwned + ?Sized,

fn is_owned(&self) -> bool

Returns true iff the data is owned, i.e. if self.into_owning() would be a no-op.

fn mut_if_owned(&mut self) -> MutIfOwned<'_, <Self as Deref>::Target>

Returns either an immutable reference to an object that is borrowed, or a mutable reference to one which is owned.

fn into_cow<'a>(self) -> Cow<'a, B>

where Self: 'a, Self::Owning: 'a,

Converts self into its dynamic equivalent as a Cow.

fn into_owned(self) -> B::Owned

Converts self into a B::Owned, cloning only if necessary.

fn is_borrowed(&self) -> bool

Returns true iff the data is borrowed, i.e. if self.into_owning() would clone it.

impl<'b, B> ToOwning for Borrowed<'b, B>

where B: ToOwning + ?Sized,

type Owning = Owned<B>

The resulting type after obtaining ownership of self’s contents.

fn to_owning(&self) -> Self::Owning

Creates an object which owns its contents from one which borrows them.
